Please hire two sombodies whose first, primary, and potentially only task, 24/7 (unless this task miraculously runs out sometimes), is to moderate and ACT ON player reports against scammer spammers.
As is stands, the most realistic scammer spammers can take days, weeks, up to a month, to finally disappear. Reasonably, from this, it would appear that the moderation of scammer spammers is not yet a priority of yours.
And it must become as such. Primo.
Surely the couple hundred you get per person who is annoyed by scammers... could pay for this.
