Have you tried mining IDENA? IDENA mining does not require a very high CPU, I think it will be safe to avoid getting banned. all you have to do is download the wallet, pass validation for the first time, then you can mine IDENA.
This guy has an idena signature, so it's more than likely he has already tried it. What's more, he had no other option, because you need an Idenq account to participate in the campaign.

I currently have VPS in Digital Ocean....
How strong did you choose the configuration server 1 cpu 1 gb ram or something stronger?
For a month or two I was mining Ring Coin on Digigal Ocean (4 cups's vps) I even managed to mine a few coins but it was more for testing than earning money. In general, VPSs (and especially the inexpensive ones) do not have strong enough cpus to to mine effectively...
I am using 2 GB/ 1cpu, 50 gb ssd disk, 2 tb transfer. I used that tier because that's all the power that I needed to mine Idena. It is really a green way to mine. not that expensive. even just a clunky laptop can work. If you have an old laptop just lying around, you can use it in mining Idena. But since I don't have that, and I don't want to open a PC 24/7, I chose to use VPS. What I spend in VPS is $10 per month. I can mine around 10 IDNA per day, so at the current price, I can take a profit of around $71 per month if I am going to sell it. But since I am not going to sell it, I will have more profit when it reach new heights as it marketcap grows.
