first of all, allow me to say congrats to you adum and the problem authors and the rest of the community... this site is popular enough to attract spam on a regular basis! =)

so... any chance u'll add a graphical word kind of filter for auto-flooders?

we could also use a "only search new comments"/"only search undisabled comments" features to make spam easier to find...

also maybe a "send all comments" (to every single problem > a list of suspicious comments for mods could also help - stuff with keywords such as "casino", "cash", "url", "href" etc and short comments (like "htryrty") and just for words without any "oiuaey" kind of ltrs... so that it'd be more easy to find and disable...

or just put'em pending for deletion (lots of work for u? but it's filtered already by mods... ;)... as unlike other disabled comments with anwsered qs, prob history and such, they don't serve any purpose being there... they're still just clutter! :)

wow, i hadn't noticed this spam before myself. pretty crazy that someone would go to the trouble. especially since there's no obvious link to the add comment page. i'm sure it's all automated... i could require people to be registered before leaving comments. or require a captcha for unregged, though that's some work for me, i guess. i'll think about it... at least i can remove URL's for non-regged users.

thanks for bringing this up,
adum

would be a shame to completly block links from unregged... maybe just make a suspicious list for mods to disabled (or better yet put pending for deletion)? but something against corruption like the 2 most recent comments at http://goproblems.com/comment.php3?prob=2238 would help... (tempting to disable html? maybe just allow only certain tags like in the forum?)

Hi,

What about to make the form include a hidden input? Its value is a cipher of the current time when the form page is generated. And the server ignores the submission if the time (the decrypted input value) is too old. The term of validity could be for example one hour. I guess the automated posting should get very difficult unless the cipher is broken.
