Actually, when you press report, there's a mail being sent to all sweepers -which are several, as you know - and as far as I remember, you can include a short message after pressing the report button. (It isn't necessary though, as obvious spam speaks for itself.) That means there is no need to write pms to the sweepers or caontact them by any other means, because most of us check their mails first when we go online.
There is still the matter of people registering to advertise Discworld related stuff, because the intention is that of a spammer, though of a more benevolent one, and we never quite cleared wether it should be treated just like the obvious spam advertising porn, wigs, and dating sites, or wether we should ignore it as long as it isn't getting annoying (say, twenty posts just for the sake of advertising something vaguely interesting, and no other contributions to the board). So, we have no real protocol for those cases where someone posts about a Discworld convention or about the fact he wants to get rid of his Discworld collection via ebay.
But when it comes to the obvious spam, the protocol is: Don't answer, press report, wait.
PS: Thanks for those who bother to report spam, anyways.
