Oh I forgot Maltesefalcon since I think he is using different username back then. I believe the main factor why most OG leave back then is the lack of VIP benefits and the tournament rewards becomes small due to profit sharing mechanism to calculate tournament rewards.
Yeah VIP rewards may be one of the factors but I'm sure there are other factors. Do you know @Onerel ? he is a player who can make $200k-500k wager a day and he did not claim Bounty Reward when playing even if he claims it he might be able to collect $5,000 per day but the fact is he doesn't claim it means he doesn't think about VIP rewards or other things, sometimes even I think they are people who do money laundering and they will avoid KYC lol.
