About regular expressions

[eddyreen]

I am using regular expressions to block spam hits.
This works really great but i do have some problems.

Some spammers will take your search term/s &Capitalize the first letter,
as i am using <_> for exact match they will get through .
Is there any way of making it case insensitive ?

Some spammers will take your search term/s &change their order like <3> <1> <2> or <2> <3> <1> <5> <4>
as i am using <_> for exact match they will get through .
Is there any way of making it order insensitive ?

I've read the wiki &some links there without succes .
Is it possible

I also had an idea:
What if Shareaza would add an extra random searchterm automattically like 'NoSpamPlease'
&then filter out any results with 'NoSpamPlease'
Could it work

[eddyreen]

Forget about my idea 'NoSpamPlease' doesn't work
It would work if Shareaza did a 'match any'
Unfortunately it does a 'match all'
Damn

[cyko_01]

shareaza regexps are already case insensitive by design

[eddyreen]

I think i figured it out

^(xxx\.sex\.girls\.)
((<1>)|(<2>)|(<3>)|(<4>)|(<5>)|(<6>)|(<7>)|(<8>)|(<9>))
(( <1>)|( <2>)|( <3>)|( <4>)|( <5>)|( <6>)|( <7>)|( <8>)|( <9>)|())
(( <1>)|( <2>)|( <3>)|( <4>)|( <5>)|( <6>)|( <7>)|( <8>)|( <9>)|())
(( <1>)|( <2>)|( <3>)|( <4>)|( <5>)|( <6>)|( <7>)|( <8>)|( <9>)|())
(( <1>)|( <2>)|( <3>)|( <4>)|( <5>)|( <6>)|( <7>)|( <8>)|( <9>)|())
(( <1>)|( <2>)|( <3>)|( <4>)|( <5>)|( <6>)|( <7>)|( <8>)|( <9>)|())
(( <1>)|( <2>)|( <3>)|( <4>)|( <5>)|( <6>)|( <7>)|( <8>)|( <9>)|())
(( <1>)|( <2>)|( <3>)|( <4>)|( <5>)|( <6>)|( <7>)|( <8>)|( <9>)|())
(( <1>)|( <2>)|( <3>)|( <4>)|( <5>)|( <6>)|( <7>)|( <8>)|( <9>)|())
(\.avi)$

This will filter 'xxx.sex.girls.<SearchtermsOrderInsensitive>.avi' regardless how many searchterms you've used (up to 9).
There is just one little hitch;
This rule also filters <1> <1> <1>
&ofcourse order insensitive should not allow multiple occurences of the same searchterm

Boaargh, good enough for me

[eddyreen]

One other question;
I am trying to block a result by it's HASH
this is how i do it;
First i select the BOGUS file for download,
Pause the download,
go to file properties,
copy the SHA1 value,
cancel the download,
goto security window,
add new filter;
content filter
urn:sha1:XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

it is not working 0(0) hits
The file is still in search results

[eddyreen]

Aaargh Shareaza hanged while adding my security rule &if i start it again it hangs too CPU 100% for about 15mins,
Where can i delete/reset the security filter when i am unable to start Shareaza

Really, i'm getting frustrated

[eddyreen]

Did a reinstall to a previous version 2.4.0.0

Aparantly it has to be like this

^(HitTerm)
((<1>)|(<2>)|(<3>)|(<4>)|(<5>)|(<6>)|(<7>)|(<8>)|(<9>))
(( )((<1>)|(<2>)|(<3>)|(<4>)|(<5>)|(<6>)|(<7>)|(<8>)|(<9>)))?
(( )((<1>)|(<2>)|(<3>)|(<4>)|(<5>)|(<6>)|(<7>)|(<8>)|(<9>)))?
(( )((<1>)|(<2>)|(<3>)|(<4>)|(<5>)|(<6>)|(<7>)|(<8>)|(<9>)))?
(( )((<1>)|(<2>)|(<3>)|(<4>)|(<5>)|(<6>)|(<7>)|(<8>)|(<9>)))?
(( )((<1>)|(<2>)|(<3>)|(<4>)|(<5>)|(<6>)|(<7>)|(<8>)|(<9>)))?
(( )((<1>)|(<2>)|(<3>)|(<4>)|(<5>)|(<6>)|(<7>)|(<8>)|(<9>)))?
(( )((<1>)|(<2>)|(<3>)|(<4>)|(<5>)|(<6>)|(<7>)|(<8>)|(<9>)))?
(( )((<1>)|(<2>)|(<3>)|(<4>)|(<5>)|(<6>)|(<7>)|(<8>)|(<9>)))?
(HitTerm)
(\.avi)$

Hey CYKO did you know that if you enter wrong regexps you can actiually HANG Shareaza
This WILL HANG SHAREAZA;
(( )((<1>)|(<2>)|(<3>)|(<4>)|(<5>)|(<6>)|(<7>)|(<8>)|(<9>))?

[eddyreen]

OK then, this is my last attempt. I've been trying very hard for several hours !

^(HitTerm)
((<1>)|(<2>)|(<3>)|(<4>)|(<5>)|(<6>)|(<7>)|(<8>)|(<9>))
(( )((<1>)|(<2>)|(<3>)|(<4>)|(<5>)|(<6>)|(<7>)|(<8>)|(<9>)))?
(( )((<1>)|(<2>)|(<3>)|(<4>)|(<5>)|(<6>)|(<7>)|(<8>)|(<9>)))?
(( )((<1>)|(<2>)|(<3>)|(<4>)|(<5>)|(<6>)|(<7>)|(<8>)|(<9>)))?
(( )((<1>)|(<2>)|(<3>)|(<4>)|(<5>)|(<6>)|(<7>)|(<8>)|(<9>)))?
(( )((<1>)|(<2>)|(<3>)|(<4>)|(<5>)|(<6>)|(<7>)|(<8>)|(<9>)))?
(( )((<1>)|(<2>)|(<3>)|(<4>)|(<5>)|(<6>)|(<7>)|(<8>)|(<9>)))?
(( )((<1>)|(<2>)|(<3>)|(<4>)|(<5>)|(<6>)|(<7>)|(<8>)|(<9>)))?
((.*)((<1>)|(<2>)|(<3>)|(<4>)|(<5>)|(<6>)|(<7>)|(<8>)|(<9>)))?
(HitTerm)
(\.ext)$

This will filter order insensitive
One hitch;
<1> <1> <1> will also match so not really order insensitive !

Why i have to use (.*) at the end is a mystery to me, but it won't work without it .

You may wonder why i am making things so complex well,
I want to catch as many bogus results as possible &avoid catching a valid result at all costs

[eddyreen]

This is what i have now

^(HitTerm)
((<1>)|(<2>)|(<3>)|(<4>)|(<5>)|(<6>)|(<7>)|(<8>)|(<9>))
((\s)((<1>)|(<2>)|(<3>)|(<4>)|(<5>)|(<6>)|(<7>)|(<8>)|(<9>)))*
((.*)((<1>)|(<2>)|(<3>)|(<4>)|(<5>)|(<6>)|(<7>)|(<8>)|(<9>)))?
(HitTerm)
(\.ext)$

The first line makes sure the result begins with at least 1 SearchTerm right after the HitTerm.
The second line matches all other SearchTerms.
The third line matches 0 or the last SearchTerm, (it has to stay there because i could not get rid of (.*), Shareaza bug )

Thanks, REALLY

Here's where i studied your suggestions (very useful guide); http://www.regular-expressions.info/tutorialcnt.html

[eddyreen]

Some Spammers think they are really smart by placing a space at the end after the FileExtension

This one will catch those 'smart' f*@s aswell

^(HitTerm)
((<1>)|(<2>)|(<3>)|(<4>)|(<5>)|(<6>)|(<7>)|(<8>)|(<9>))
((\s)((<1>)|(<2>)|(<3>)|(<4>)|(<5>)|(<6>)|(<7>)|(<8>)|(<9>)))*
((.*)((<1>)|(<2>)|(<3>)|(<4>)|(<5>)|(<6>)|(<7>)|(<8>)|(<9>)))?
(HitTerm)
(\.ext)(\s*)$

[eddyreen]

Inserting all these rules is a lot of work &I am veeery laaazy !

I was thinking about writing an AutoIT script;

-Abort when maximum limit of rules has been reached .
-Look for a file that definetly does not exists .
-Insert a new security rule if it hits that will time out after XXX .
-LOOP

It would be even better if I wrote a plugin, but unfortunately I lak the skills.

I really wonder why noone else has had this idea before .

Does something similar already exist
