In practice, I have not met any complaints about blocking accounts on the pool for this reason. If you are a respectable miner who has been mining for a long time and does not cheat, then you will not have any problems.
Any statistics of payments can be tracked on the pool, and if your result is doubtful, then no one wants to lose their money.
It sounds like you are using Hiveon pool, I got scared by their pool FAQ that stated that once your stale shares reach 5% you aren't going to get paid at all and I'm already at 2% lol so I stopped mining on the pool and switch to another, im sure you have stale shares, have you reached 5% before? If No what are you using for internet connection ??
