I have had mixed results with moving house/new accounts, I think you won't get far past registration or verification so worth a punt.
Do you not have the email account linked to the gubbed accounts? As most should have sent a "information about your account" email (the recent spate of GDPR emails with similar subjects kept me on high alert
).
I am still a member of PA and love it though I am on the old pricing structure, you will find plenty here who also rate Odds Monkey and Yes Bets - personally I think you are fine with either of the big 3.
A quick update on offers; some of the big intro offers have lowered their amounts (e.g. bet365 and 10Bet now £100 each) but new ones pop up here and there so should be some profit to be made since you stopped, horse reloads still going strong, assume ACCAs are as well but don't really do these and probably the most popular sport offer is 2UP (bet365 and Paddy Power) which is luck of the draw but can bring in huge profit.
