So just more assertions with no evidence? Huh.
You may be right about some of those things though. If enough words come out of your keyboard, eventually even you will be right about something.
ACR is the only offshore US-facing site I know of that has their poker RNG certified by an outside source, with a legitimate link to the certificate on their website:

Ignition claims their RNG is certified by the same company. Maybe it is, but good luck finding that cert. There is a link to a cert on their website, but the linked certificate doesn't cover real poker, just casino games like 3-card poker.

Maybe other US-facing offshore sites are certified too. I have not looked into it, and we can say with confidence that the Madman hasn't either.
Ignition limits SNG multi-tabling to 4 games. I've hit that limit before. I don't think there is a limit for MTTs, or at least I haven't hit it yet. I don't know about cash games.
ACR's limit is 24 tables.

I don't know about the other sites multi-tabling rules.
I don't know what each site is doing about "fighting collusion and such", and neither does the Madman. ACR once had me do a Captcha-style test at the table, FWIW.
Ignition's PaiWangLuo network has more players than ACR's Winning Poker Network, which is a good showing for a site that doesn't "even try."
