Same here, once you got the limits the site is dead.
They are basically showing you the door. Both stake and sb.io did exactly the same to me. While stake only limited me for certain sports sp.io did it for all sports, its ridiculous.
I know that the limitation is from the odd put so I believe that there is no platform who is a gambling platform that would like to limit it players except that there is a strong thing that is behind the delimitation so if you take very well that you will notice that yes there is some particular area that you are faulty which is a hidden thing so if you verify well I think you might know where are the last season's coming from
I try to bet as much as possible on promotions proposed by Stake but I never cheated (back multiple sides, etc ...). I usually take some info from tipsters and I bet often on lower leagues to have value bets or surebet sometimes, but frankly if betting on exotic league or markets is suspect in this case they might as well not propose these markets.
I never use large stakes for my betslip, most of the times from 1 mBtc to 3 mBtc and as far as I remember I have not set any betslip with more than 15 mBtc.
