The bigger problem with this slow chess is that you play computers all the time. Theer are ways of avoiding it (check members ratings and don't play with people with 1100 blitz ratings and 2000 standard ratings for example) but the easy availability of chess engines has doomed slow online play in my opinion. It's really too bad as I would enjoy snuggling up with a cognac and a friendly 30 minute game but playing Fritz over the internet is just pathetic (yeah...it's better than me. So what?)
Yeah. I've been learning how to tell if someone is cheating using a chess program. It's not always easy to catch though. And if you do catch it, there's not really much you can do about it unless you can somehow prove it. As for the low blitz rating and high standard rating, I don't think that is a really great way to assess whether or not someone is cheating. I would think that even great blitz players would do a little bit better in a longer game because they have more time to think about their moves. Less chance for a blunder. But so far, I don't feel like I've run across anybody who was cheating. And if they were then they were using a really crappy program because I generally hold my own against people with similar ratings.

A little comment here...
Premium members can play multiple games at once (or so it says when I do something that looks like trying to play a second game). That would permit you to start another one while waiting for the other to "reconnect".
A player who disconnects in a long game has 5 minutes to reconnect. It may seem boring to you, but when it happens, you know you would have won. Just take a break, go to the restroom, have something to drink or whatever; if you're like me, you tend to have troubles leaving the screen once you've started playing. Patience is part of chess; being in control of your emotional turmoil also is. Angry players make more mistakes than cold players.
I also remember way more people disconnecting when I had a way lower rating. It's weird to say "improve and it will get better", but it's true. It won't happen in a snap of your fingers, but the lower ratings have those who are new on the site and don't know its policies yet; it also contains those who chronically disconnect.
Little mention; I had an internet problem, something throwing me to another page WHILE I was playing chess, usually right after the first move. Eventually, the site made me "lose" the games when it happens. Those who chronically disconnect DO have that consequence after a while and they learn or they don't.
Playing multiple games at once!? Hahahaha! No thanks. I get my ass kicked enough just playing one game. But in all seriousness, I see where you're coming from. As for the "improve and it will get better bit". That doesn't really help me. Regardless of people DCing or just being general jerk-offs, I'm always trying to improve. That's just a given.
