Well I've put him on ignore, so he won't get any merits from me.
I really must formalise my ignore list. I forget why I'm ignoring people after a week or so.

Jajajaj, yes I was tempted to put him/her in ignored, but given the strange behavior, I rather prefer to keep an eye, though. I just don't know what to think. It doesn't seem legit, but I would be glad to see other's insight (and then put this one into my ignored list).
