The one being accused is part of a farm of accounts which have been hosting ANNs of shady projects in the past. If you follow their posting history, they have been one liner spammers for a long time in this forum and been recently recruited into posting ANNs.

But the copied whitepaper gives it away, bunch of lowlife scammers they are indeed.
