Thanks for the info re 5 mins. That doesn't seem much of a punishment, given that they often cause the other player to have to wait for more than 5 mins whilst the time runs out.
I don't mind if someone loses power. It's the prevalence of this happening precisely AFTER you have just made a winning move that bugs me. (i.e. it would be a strange coincidence if they just so happened to lose power at such a time.)
The site says that players may have their account restricted in accordance with the 'fair play' policy. What actually happens? It seems to be very prevalent that players will simply log off, leaving you to have to wait for their time to elapse. Could the punishment be increased to discourage this further?
