Some writers drive me crazy.
They change their book icons in signatures, so I have to re-block them again. On the other hand it became a sport for me. The moment I see a pic in the signature, I immediately block it and grin

However, people who put pics in their signatures only frustrate me. If they think there is a remote chance I will ever click on their ads or read their books...tough chance it is.
Maybe if I come across their books somewhere else, then I would not even know it is the same "blocked" nuisance from forum.
