Uploader is a sockpuppet account of a serial spammer, who uses such tricks because his more overt attempts at free advertisement were terminated due to him spamming the hell out of everything. He even tried to bribe other users to post his garbage, after creating nearly a dozen of other sockpuppets. This is just a most recent incarnation of the same scumbag.
Since I do not visit forums, I'll leave credit farming by alerting the powers that be about this issue to anyone who cares about doing so.
