Could be because you are low rated. People don't cheat in order achieve 800 rating, usually they want to stick around or over 2000, so they create new account at 1600 rating and then trample over us who are between that and their goal...
There's a way to trick cheaters into losing it's not as hard as you think
Chess has this way of making you feel like every loss is a testimony to your utter stupidity and every win a way of making you feel like everything is possible if I work hard....
"Don't get too excited when you win, don't get depressed when you lose. Always remember that in the next game everything can go the other way."
