Blizzard is trying to drive all legacy players away (they want you to buy sc2/wow and play it) by ignoring all problems in Battle.net.
Starcraft - Tons of hacks and @@@! which are making the game unplayable.
Diablo 2 - Bots, hacks and spam, making ladder pointless and public games pain in the ass
Warcraft 3 - Hacks, host bots
If Blizzard cared, there wouldn't be any problems.
I have lost all faith in Blizzard long time ago. Blizz belongs to my "Top 5 worst game companies ever" -list.
