Using a different address is always going to cause problems I would imagine, as there will be other people (in a lot of cases) with the same name and DOB.
Email address and phone number should be disregarded as they can be changed far too easily. I have unlimited email addresses, of which very very few have been used at more than one casino, so instantly, me signing up to Gamstop would fail one check on login. I also have 2 phones and could get a new number in about 10 minutes.
Funny how it was another LV customer though, loads of threads about their RG failings recently. Other major license holders don't get anywhere near the same amount of complaints on forums and suchlike it seems, none of the major bookies, all of who have much larger customer bases than LV, Casumo, probably around the same, BGO etc.
Oh the bigger ones are bad as well. As part of an investigation I was able to open up 4 accounts with WH despite being excluded by changing email address and being a day out on DOB. Betway verified me with a wrong date of birth despite holding an exclusion and after sending correct Photo ID clearly showing a difference. BGO, K8, Dunder also fully verified accounts(had to min deposit in each) after 72 hours despite wrong info again. The whole thing is a shambles. Actually brand's like Nektan, L&L, Everymatrix, Ladbrokes, Coral, Videoslots, Trada and most others are doing things properly. I was stopped from opening accounts based on a name and address match to an excluded account, this is how it should be!
