Thanks for your interest. Unfortunately based on the post count, you have not quite met the "active" qualification for the moderator role. You can, however, still help in maintaining the forums by sending a report when you see a spam post. Just hit the red triangle button on the top right corner in the questionable post to do so.
I usually just ban new user who posts spam link (unsolicited ads that are not related to Urho3D or gaming development in general) without any prior warnings and also delete all their offending posts. A few artists may also attempt to promote their assets by posting unsolicited ads/links to their website in the forum, for such case I normally just send a warning stating that our forums do not allow unsolicited ads, without banning the user outright and delete the post in question if it is really out of the blue. But that's just me.
