I have not seen any way to get to a member and block them, whether using the most recent messages or whatever method.
I did a search on block members and nothing comes up. Perhaps you told Don not me?
and yes, the SMF is very versatile but sometimes tools are turned off for some reason. Id think blocking members would be one that they'd have available for everyone.
also fyi I don't block people unless they are just useless spammers such as the individual(s) we have that are getting more frequent with it. It'd be nice if we had some actual mods though that would cull this shit. Looking at the two listed admins for the board, one of them posts every now and then, perhaps they can give some members here the tools to delete spam, or move spammers to a status where they can read but not post. SMF does give the admins abilities to make groups and basically fine tune who gets to do that.
It's only a matter of time before the find girls in your hometown turns to them posting porn on the boards, THEN the shit gets picked up by the crawlers and this site gets blacklisted pretty much everywhere.
