For all having issues with rejects -
-- Keep intensity below 19, try 18 (on -g 1 configs).
-- Insert -E 10 -s 5 -Q 0 settings into your config(s).
Can you explain why you are suggesting this?
Lowering my intensity lowers my overall hashrate - and on other pools I have close to 0% rejection rate (only here do I have a higher rate)
Can you explain what -E, -S, and -Q are as well, what their default values are, and why you're changing up or down instead of giving blind advice?
Even if you lower your hashrate, (by the way, everyone knows that lowering intensity = lower hashrate, so no need to tell us) you still earn more than on other pools.
If you don't like CleverMining, then go away.
