Normally I would not post someone else's comments but I thought they were well-reasoned, sound, and fair so here goes:
There are plenty of Revolution skins that player their non USA players very fast. Take Comeon or AdamandEve. There are a few others as well I believe that pay quickly (they have their own cashiers).
Cake has been really bad for a long time, since the big Doyle's room thing at least I believe (lots of debt, interesting Subject Poker stories on that when they interviewed the guy from that hyped up poker room that was set to move to UB/AP before BF, forgot the name, the one with the steroid Dan guy).
Lock, I'm surprised they're still around, but I think growth has fueled deposits for longer than their EV was two years ago. The growth was only partially fueled by the crazy grinder rakeback that was provided, a lot of it has to do with networks like Bovada and Winning taking the (smart imo) approach in a short term market of making their margins NOW, rather than acquisition (which would make more sense if you were in a long term market). And Merge has gone that way too, so the only choice for the endless drones of "highest rb % is all I care about" and "hype hype hype" is Lock.
Anyways, since their post black friday slew of scandals and lies it seemed this company was biting off more than they could chew. Read some of the promotional material from how much better the switch off of Merge would be and how everything was a Merge problem, it's humorous to most in hindsight, though unsurprising to most that have been in the industry for awhile, I haven't met an industry guy that has believed in Lock for awhile. Even most affiliates of theirs I've talked to haven't bought into them for awhile, but the money is too good to pass up. Same for a lot of pros.
At least if/when the **** hits the fan on this one, nobody can say they weren't warned/the info and warning signs weren't clearly there.
I guess to play devil's advocate, they could have player money and just be the worst at processing moneybookers/neteller, bad at processing USA, really greedy about short term margins (restricting cash flow) and they just happen to be dirty liars too (casino bonus scandal, girah "lawsuit" are two fairly known ones). I would fade that prospect hard though.
