To avoid LPQ:
Don't draw attention to yourself
Don't use voice or chat except for 'ss'
Mute all at lvl 1
Only play in parties
Get alternate accounts
Limit your usage to one or two games per day per account
Don't play too well
Don't play on Sunday or Monday
Wait until the developers reset LPQ status
