I noticed a strange behavior from a user of Math SE, I have no means to contact him directly, so I thought of notifying moderators of the site by flagging(may be).
There is nothing related to flagging a user from his profile's page, so I guess I'm left with only the option of flagging one of his Questions/Answers, which seems inappropriate to me, because to be honest neither his questions, nor answers are the subject of me wanting to flag him.
EDIT
I noticed this user is using the site almost only to ask questions, he doesn't even bother to upvote/accept answers on his own question
[upVote: $\frac{0}{50}$] [accept: $\frac{3}{50}$]
I thought an act like this is not of the benefit of the site, I don't mean only showing appreciation to the guys who helped you (which is a common sense matter), but also the way one interacts with the site may harm it.
P.S: this user is enrolled for more than a year! not a new comer [like me :) ]
