Possible shady DoN reg on merge (Wizowizoo)

I've recently started grinding don sng's on merge when I came across this player. From what I can tell he is a pretty decent player that grinds $3-$10 don's. When I searched for him on sharkscope I noticed something very odd. He has these wild down swings which are basically straight down. As you can see from the graph below he puts in some very good volume so I find it very strange that he would just start spewing off in $100-$200 sng's. He is also up $18,300 in MTT's according to OPR which is very close to the number he has spewed off in sng's. Maybe he just likes spewing off his bankroll in high stake sng's even though he has played over 14,000 sng's and is good enough to have won 18k in MTT's. Anyone have any more information on this player or is it possible to find out if he has been chip dumping in high stake heads up?

Sorry about the size but I ran out of free searches and this is all that was in my history.

Don's are very bad for collusion probably on all networks.

Another game that's bad are the hyper turbo sng's on stars.
I recently received a refund from stars with an e-mail that stated
certain players were violating the terms of service and I may have been
adversely affected. No other details were given. I would have liked to know
how they calculated my refund at least.

Neveragain will I play hyper turbo sng's on stars.

Firstly props to Stars for doing the right thing in providing a refund.

This has happened before, but they will not tell you anything about the way funds are reallocated back to players.

The don's have been removed from stars following collusion by large chinese gangs, not before they got away with a huge haul.

is the PokerDB still around ???
