His offer may be interested (as in recruiting for his FC) - though that still beats half recruitment offers on this game, where you just see an invite poping out of nowhere.

Or he may be "just friendly" (Yes, those people exist). Or lonely. or whatever.


As long as his offer to "help you leveling" does not include sharing account, I can't see what he could do to you (as far as scam/hack/... goes).

Just stay on your guard for what he may ask of you in the future (activity or personal info, RL or web-related), but so far, no reason to cut ties or fear this guy as far as I can tell.
