We all know that there are MAJOR problems with signature spammers on forums and mod's have a right to call any member on it when they feel that it becomes blatant.
In fact inaction on this matter devalues forums so I am for smashing signature spamming in any form it comes in, not accusing you of this Janeth because I have not been watching the situation.
I am simply making a statement that signature spammers are a cancer on the entire forum circuit, many are using forums for
SEO and that is link dropping, in addition many of these spammers are getting reported to Google now days.
