I don't think you need to go to such lengths to prove they are real people. By all means make a great and meat if you guys like to hang out but I don't really believe anybody would pay 2mBTC for multiple accounts in fantasy. There is enough work managing just one account.
Not especially having to play in all league pools available (except F1, of course), why anyone put themselves through sure mental torture, but we've seen worse playout on this forum, I mean speaking of the guy that had, multiple account while back in the Chipmixer campaign, with was it 20 other accounts in different campaigns ?!
And more so, for FPL I strongly don't think you'll get an edge for having multiple accounts for 38 game weeks that are often dynamic, you'll just make the right calls in some for a few weeks and otherwise for the others, then after a few weeks the scenario would likely be reversed, the only edge I can see is probably the weekly prizes, which they'll already be ineligible for.
That said, I'd also rather not have such complication, and I really love the banters here with our small squad, but if we can have 30 people from the forum in here, maybe from the PL Pool regulars this time around, why not? that'd make the banter more worthy, I believe! and if there just weren't so many pool to join each season, I wouldn't mind a higher entry fee of maybe around $150, because the FPL and the way it works obviously isn't a competition you win by just being lucky.
On the side bet, I'd rather not take two side bets in one competition, it's funny that you were once my usual side opponent, and it was Igebotz that struck my mind first this time around, maybe because you really don't rub it on my face when you take my money for free, but Igebotz does and I wish to go on a 10-20 side bet winning streak against him, but if he opt out of this, then you're on!
However, Buywatress isn't someone that'd shy away from such side bet either so you can throw the offer at him, at least with you both being Liverpool supporters, one of you "Will have to walk alone" away with the other's money
