Something like Bad Behavior?
I've just noticed the link on the bottom of this forum and checked it out. Looks impressive. Perhaps something like BB might be a good option for "Insert Name Here", especially for installations of it on shared hosting. Anything that could limit resource use and reduce bandwidth has got to be a good idea.
Working on it, looked easier at first, but has to be implemented properly to actually do anything.
No worries, Sheepie. Implementing is always harder than it looks. It's a rule.
