I remember about a year ago, I was ghosting an irl friend while he was 4-tabling NL10. There were a lot of multitabling regs, and alot of them were the 11/5 set camping, uber-weak tight nits (and this was 6max). I was actually kind of surprised. Still a profitable player to play against obviously, but nothing like the whale with a vpip > 50 that calls down any piece...
SInce I'm rebuilding again on 10NL, I noticed this trend...they either make abysmal calls or abysmal folds. And they are still ATM's, because their game is grossly unbalanced.

This is my recent hand from 5max 10NL :

UTG opens for $0.5, donkish leaky player pops to $1, I see QQ in hole and make it $2.5. UTG folds, leaky player calls and checks QT5 board. I bet half pot ($2.6), he types in chatbox "KQ" and mucks.

Another 10NL hand (fullring):

I open UTG with AK 4x, UTG+2 calls and rest folds.
Flop QTT. Check/check
Turn blank, I bet 0.7, he minraises to 1.4, I make it $3.5.
He tanks, types "QQ? i have AQ" and mucks.
