Ive tryed it, they suck. having someone competent with a script to change their their IP really fast is more effective. if you have a normiephone, I've seen those can change theirs faster than resetting a router sometimes.

they do have tools to mass delete images based on things like filename and dimensions. I think they blocked some of trev's ron paul images. There was a case where they tried to use it against some anime screencap spam quite a while ago if I recall and it caused a lot of false positives and pissed people off.
This would be an effective tool for creating a spam folder.

Honestly, I dont have high hopes for this, having a large group of uncoordinated people and trying to coax modern normie /b/tards doesn't have a high chance of working.
Best chance is a small group of IRC neets who know what the fuck they're doing and have lots working proxies and something similar to delayclose. I dont even know if the last version is working anymore with the way they've tweaked catchpa to prevent that kind of thing in the first place.
