Could be trying to game the Karma system I suppose, assuming this system is every used for anything "tangible" in future if you know what I mea. Only the Har4oo2 account is linked to maemo.org but the n0ak account could be linked at any time in the future and start accruing Karma resulting from these suspicious "Thanks".

I would be inclined to suggest the Thanks applied to n0ak by user Har4oo2 should be removed from the t.m.o database and the Har4oo2 account banned.
