How much evidence is needed, for you to believe that a communitypool is a scam?? For me it's obvious. You should do something. Take this pool off from the first page.
Maybe the SCAM is too harsh of a word ( unless someone can prove somebody is doing it intentionally...give them the benefit of the doubt ? )...but I can also confirm the return from community pool is much lower than expected. I mined on cyrpto.cc and cryptopool.space as well, I have the feeling the last one is the fairest one.
One thing I really really disliked about community pool it was the fact they were updating my pending balance at very long intervals, and that makes it hard to have an accurate estimate on how much they are funneling to their wallet. If the update would happen after every 1-2 confirmed blocks, would be much easier to pinpoint how much we are missing (I'm estimating 20-30% at least)
