Hi Vic,

If you learn Computer Science you know that it's possible to fake an ip-address. It's possible so that disqus thinks that packet comes from a.b.c.d while the spammer has ip address b.a.c.d or something. Offcourse Disqus can't sent information back to spammer.

Wow, I hope this doesn't start happening to me. I chose to go with Disqus to avoid this problem entirely.

@Vic: On the note about the "same IP address" -- that's the whole problem I had before Disqus. I'd get hundreds of spam comments in a day, each from a different IP address. Occasionally, a few would match the same IP address, but it was so completely spread out that I could just start blocking by IP. In fact, MovableType will automatically block by IP address if it gets more than a couple in a short period of time, so the spammers must rotate IP addresses to keep getting through.

The worst part about comment spam? It's worth their time. People click on their spam and buy their products. Erg.

Not user if DisQus folks are using an IP based DELAY filter for subsequent comment submissions from the same IP address. Typically SPAM bots use the same IP address and try to dump the hope SPAM load in a period of time before moving on.

On multiple comment submission attempts from the same IP address, a machine challenge or simple comment rejection and banning that IP for say a 24 hour period should work great.

The normal folks just dont submit 20 comments at a time - this is simply not human behavior - and could be used to identify spam.

My 2 cents. I am sure DISQUS has lot of smart folks.
