My 2 cents:
Any SE-ed player is mostly an experienced gambler who most probably knows the ins and outs of executing an SE and the consequences, especially in light of the latest publicity the UKGC, the fines etc have had in the UK
At the same time, addiction does not let you go that easily, so you open a new account somewhere else. Now, in any normal case you know it will get you into trouble if the sites are somehow connected and therefor you will double- and triple-check that that is not the case (you will do this even when you did not SE due to gambling problems). Royal Panda has this little gem at the bottom.
So, next to the SE itself. Gamblers, especially addicts, are mostly well informed what the red flags are when registering (if not from anything else but from failed new registrations due to an SE at various sister sites). There are also forums for UK and other players, where tips are exchanged, e.g. which details/errors pass the initial check at which casinos. Don't ask me, I won't give you names.
The OP must be the umpteenth player claiming they misspelt this or that and are blaming it on dyslexia. You do know there are online tools for dyslexic people that help avoid exactly that?
My conclusion:
The OP knew exactly what he did. He has been tipped off that CM has a good RP rep who will probably help him get at least his deposits back so he registered at CM and "tada" deposits are back in his account with the advice given by CM members and now he "smelled blood" as he sees a chance/loophole to also get his winnings.
As always, I'll happily be proven wrong just for the sake of the OP getting his winnings.
@EkJR Section 17 of the LCCP states they must identify the customer but it does not clarify the type and amount of discrepancies allowed to let a customer start playing while asking for additional docs or clarification. Any procedure/software allows for some percentage of error to avoid too many false flags. Pretty sure that the UKGC discussed and agreed upon that in consultations with casino operators. Surely something they will not disclose publicly as it would give info to exactly those people who try the SE trick.
As for being part of a company group, you can refer to SR code paragraph 3.9.1.4
