I've looked and looked and can't find any way to disable links in signatures.

None of our regular users use links in their signatures...just quotes, etc and sometimes an image...which is ok.

Lately, there is almost a daily trend with spammers that register with links to their websites in their signatures and engaging in silly questions that sometimes rope our faithful members into wasting time on answering them. It is just the past two weeks or so we've seen this and I ban them, but they keep coming ...maybe one every other day.

How can I turn the ability to put a link in a signature off? The path to it in cp would be appreciated.

Thank you.
