So I lost a bunch of coins today and yesterday with hashrapid, and now I'm still getting charged the 2% fee, even though it is supposedly waived. Hashstrike has been pretty good, but tonight after 30 minutes or so I get a message in cgminer that I'm "temporarily banned" from the site and cpuminer loses the connection. If I stop the miners and restart, they will work again for a while.
These 2 sites seem to have the largest amounts of miners, but I'm wondering if anyone else can recommend a good pool.
Thanks
Workers are banned when your invalid shares percentage is over 50%. I'm not sure what miner you are using, but if it has an option to not submit stale shares that will help a lot. If you're using a lot of small CPU miners, you will not have a lot of luck... we can set up another instance for small miners with a lower minimum difficulty, but it would likely be a lot of work for not much return, since CPU miners are so much smaller than GPU miners. Sorry

The details for our pool (which are teh default, and you'll likely encounter on other pools) are:
WORKER_BAN_TIME = 300 # How long we temporarily ban worker
INVALID_SHARES_PERCENT = 50 # Allow average invalid shares vary this % before we ban
