 Posted: Fri Aug 19, 2005 8:55 am Post subject: some regexp problems |
 |
|
Hi,
i was working on spammers a while ago and im back again. but now spammers get developed. they really got weird spam methods.
here are some of the examples:
ºwºwºwº
I¤R¤C
(using with color and it seem like w w w and I R C)
lots of thing like that. i think they all can be catch by using "regexp" but i couldnt figure it out. i dont wanna add all spam words which i was doing to that time. speacial charecters allways changing (, . ? ' ( ) and words). i want to catch them if there is "w w w" in the sentence. it doesnt matter where they are. (ex: where is will wonder) <<-- that person must be caught.
got an another problem, the channel im protecting is at about 300 person and its very active i m using greet message to catch some kind spammers which are using the way "away message". so i have to message all the users but when i give that work to 1 bot it get lagged or "eflood"ed. so i want to cut it to half. if nick starts with "a-k" message else dont if nick starts with "k-z && "special charecters??"" message else dont.
sorry for bad english, i tried my best. thanks

You could remove everything thats not a normal char or a number from the string before doing any regexp matches on it. | Code: | | regsub -nocase -all {[^a-z0-9]} $line {} line |

Just think what will happen to "vist us on http://www.mystupid.ad and our #stupid-channel". yes, it will become "vistusonhttpwwwmystupidadandourstupidchannel". Good luck  .
you won't be able to find advirtising spam that way, you should keep at least the characters " ", "#", "/", ":" and ".". So I would rather prefer: [^a-z0-9\./:# ]
However, for general purpose stripcodes is the best and probably the fastest solution.

this will strip mIRC color and control codes:
| Code: |
regsub -all {([\002\017\026\037]|[\003]{1}[0-9]{0,2}[\,]{0,1}[0-9]{0,2})} $str {} str
|
and this will match a hotlink (clickable URL) or chan ad:
| Code: |
regexp {(?i)(http://|www\.|irc\.|\s#)} $str
|

| so what do you care if they use another method with no clickable links? nobody will bother to manually strip the spam and paste it in their browser - people are lazy, spammers know that; spam without clickable links is harmless (annoying yes, but that's all about it) |

| if you've managed to write some script satisfying some of your needs, you should be able to grasp the [regexp] concept and eliminate nick patterns that are of no interest to you, it's not that hard |
