Probably ... but still it doesnt mean anything.
You play bad, you re playing badder and badder you loose patience, loose queen or whatever in the first moves and then give up (and i dont think you can give up before 10 in arena no ? ) .. and if i lost like checkmate in the first moves then hell yeah i was drunk or pissed or just had fun. And it happens to me too to try some mistakes from begining to UNDERSTAND in real situation why we must not do this opening (or absence of opening in that case). it s called experiment i think.
But then again i have to justify the way i PLAY ..
Well i am lying actually, i didnt have to jutify as i have been banned without warning
Anyway it s no big deal ... just wtf 
that make them do things like this ... but please they could work on the attitude and at least say "sorry for you " hahaha ayayay anyway i still loose all my games like they cursed me
So few days ago i learnt what Sandbagging is ...
New to this game/site i enjoyed a whole new world, and then after a month i suddenly cannot play arena anymore... "mmmm why is that" then i thought.
And i notice this little white window with a story about a "sandbagging" situation.
First i didnt check the meaning of this word/expression because i thought it was about of network or some kind (i m not an english native speaker as you could probably see).
And so to make it simple and short : after a day or two i then check and learn that i am "accused" of something i dont even understand the reason why i would want to do something like that ....I mean, aside the fact that i tried day and night for a month to reach 1000 and that from my side it s the sumum of illogism, are such petty and cheap people really exist ?
of course they are i guess but wtf ... Accused AND punished (i enjoy arena a lot) without trial .... i overplay this drama for fun in that note of course, but still it s not a nice feeling and i really dont understand this website (chess.com) in that case.
Insulting and punishing their suscribers (i payed 90€ or so) just based on ... what ? i lost "Elo" ... yep it happens to play drunk or tired or angry or extatic or whatever the fxxk is your state of mind when you decide to enjoy playing a game on internet (or a sport whatsoever).
And just to share something i found out : a 300/400 Elo plays almsot same level as a 800/900 (reason why i lost so much in a night, and still cannot go back up to 850.
As a matter of fact i am now 300 and loose a lot ... but yeah it s a big plan to win an arena and feel happy about my fake big virtual di.. oops sorry : intelligence.
I dont even have words. Actually i ve not been accused of being a cheater but simply a capital A asxxle. And when i say "I" i talk about that behaviour in genral and that this policy i not only stupid but can be insulting, and unfair for everybody.
My 2 cents.
Ps : i still cannot play arena after 3 days and a mail to the chess.com team (they answered nicely i guess, but i still waiting).
