I will say it again I don't see any reason you should not fire the normal pool up again.
I'm sure hashrate would land on it now with everything going on.

Keep lucky everyone <3
It's just one solitary miner. They could disappear at any time. A regular pool needs even more hashrate than solo currently has, or it will never attract other miners. In addition most big miners are run by committees and have stakeholders and shit that demands regular fixed income. This is why FPPS has taken off like crazy - a payment scheme that no small pool can afford to maintain. Whilst PPLNS is the fairest system, most if not all big miners aren't interested in the volatility of it.
As -ck said, it's just 1 miner. Considering their massive hash rate, solo is the best way for them to go.
Thing is - if they were part of say, 'the other' small pool (or any other smallish shared rewards pool) and running on the PPLNS side, sure said pool will be hitting blocks just as often - but even Kano with his 9-10PH there would literally only receive a very minute portion of the reward vs current payout with the pools current hash rate.

That is exactly what happened to Kanopool a few years back - The one company behind a huge chunk of miners broke up and took their hash rate with them. We have yet to recover that lost hash rate
