That is only a small part of the spam that posts and is not only one person.
We try to catch them and some are caught in the spam filter, but they are getting sneakier. It is a constant battle trying to make changes to stop them. There are quite a few that don't even make it on forum. Not every post is stopped for approval before it goes on forum.
It is very appreciated when members report suspicious posters, spam, copyright violations, and guideline violations that are on forum, as we can't be in all areas at once. We can have just left an area or thread and something comes up.
Thank you to everyone that reports these to us, it is very appreciated.
