Is anybody managing to keep a profitable sportsbook account open?

Not just here, but with any of the highstreet bookmakers.

I have had heaps of accounts in friends names and tried lots to keep them open. I always have a few decoy “mug” bets but I’m reluctant to in essence give away more than a couple of quid on each of these. This worked before but my last batch of accounts were scrapped once I had one big bet decent on each. I have my tracks covered re IP address and cookies.

The only way I found I could get a solid amount of time out of an account was either inherit a long term (1+ years) losing account from a mug, or have lost a lot myself from decent stake mug bets which is pretty much the same as the first way. Both of these I won much more than the initial loss but obviously I’m not keen on purposely losing lots of money in hope that my account will last more than the usual few days.

What tactics have you guys found the most effective?
