most posts in those discussions are complaints of problems, so your site probably doesn't have a lot of problems.
however if you want feedback, i use the site from the beginning, i make 10-11 claims a day and i always got the minimum claim (the one between 0-9885) never, and i say never, got the number beyond 9885.
this is the only site, with such a system of claims, in which i have never gone beyond the minimum claim
Thanks for your feedback.
We are using FreeBitco.in ourselves, for several years now - and we've never rolled more than 3rd prize in that site, and we use it on a daily basis - so our sites are programmed in the same way.
