Do you know what I was told after I opened ticket on support? "We suggest you disable your CPU" did they tell me to turn off my rigs? That's right ?
Are you sure they aren't just telling you to turn off the CPU portion of their miner, so it only uses your GPU's? That's how I would read that - not that they're telling you to turn off your rigs.
I think it's pretty unlikely that they blocked your IP because of the post, I've made positive and negative posts about Nicehash, and have never seen a comment one way or the other. They do have some kind of automated temporary banning of IP's if your miner is misbehaving, and I have run into that a long time ago, but if I remember it was reset after a few hours.
Right, I also don't think the IP ban is related to his reddit-post in any way.
Can't see any benefit for NiceHash if they manually trace people posting that they're shutting down their rigs on reddit and IP-ban them.
I'd prefer manually mining on a pool anyway.
