Most forums have dedicated categories for common stuff like this. Written reports are fine if an explanation is needed, not for the newly created samename37 spambot account illicitly selling drugs (or something that is probably phishing, like the delta airlines refund ticket type stuff) without really doing much to hide it.
It's the same communities and overwhelming at times to the point it doesn't even feel productive or even needed to report it. This is the lowest of low-hanging fruit.
