This user might not be a scammer but a victim of a scam. Maybe he has run into all this scam investment platform where he deposited little and somehow they were able to increase his profit to a certain amount, which will be tempting to him to want to withdraw, but they will not allow him to make that withdrawal (because there is no coin there in the first place) instead they will want him to bring money deposit which he will never be able to withdraw back, and seeing this amount, he will be moved to go ask for a loan from anywhere he thinks he can get it based on his greed to get those figures on the platform, which is not real.
Yes, but he then rushed to the lending board asking for a no collateral loan. How did he know that users give out loans in Bitcointalk?
Well there's one answer, He's probably an alt of a past scammer trying out all tricks and luck to acquire an unsecured loan. He definitely knows how things work in the forum.
