I don't know how feasible it would be to add but I think its needed with the constant bombardment of gilsellers spamming shout. You can blacklist them and then a new one pops up less than an hour later. Right now, they spam the same message but add a random number at the end so the shout goes through. I would hate to cause an inconvenience to fresh players that find the server but geez, this is really getting annoying. As far as I can tell, the chat filter to exclude it doesn't seem to work.

I was thinking that maybe /sh could have a filter, so they can't tell ya about the website. Just keep adding whatever they come up with over time, until they can't give address of website. However the level requirement is a much better idea. If a mule needs a shout, could always ask someone running around for help with a shout.
