I havent aborted any games. The server , however, aborts at least 3 out of 4 of them. Why is this happening, and why have I been restricted ?

You need to make your first move quickly (20 seconds), or the server aborts the game. Could be down to lag, but that's probably the reason.

Move quick! Move quick! Or else the time shall tick!

Seriously, though, you have 15-20 seconds to make your first move; otherwise, the game will be aborted. Chess.com's Fair Play Policy restricts users who abort to many games.

And trust me, it needs to be a LOT of games, so you probably have waited too long in many of your games. The server aborts the game after you wait too long in case it has been abandoned.

I was playing a game and the opponent was going to definitly promote i only had 2 pawns left... so i resigned the made me wait 5 minuits for always abandoning my games!!!

dear server, I do not know,why you shut me off most of the time, I did not do anyting wrong, I have a very bad internett conction, wich  occur during my game, so I loose most of the game, so you punshing me for somting not up to me, Im enjoing being a part of your chess socaity, but you do not give me a chans, thank you, regards, Oraby.

bad internet connections cause game abandonment, unfortunately.  not much chess.com can do about that.  :)

Possibly a technical error.
