Yes - as NotFuzzyWarm stated it is now allowed for that exact reason.

The main issue with most if not all miner developers, is they are hackers without any tertiary computer education, and haven't worked in the computing field doing any sort of critical software development.

They wont test their software properly and expect problems to be the problem of those paying exorbitant fees for the software.

So here, with hack firmware like the apollo and braiins, I required them to find a >32 bit share before risking them running on pplns - since mining on pplns is forcing sharing that risk with everyone else on pplns.

Also, for the same reason, since I'm the largest miner on the pool, I don't want to be sharing my rewards with people running untested software that might throw away blocks.

Bitcoin mining is abound with known license violations and hack software.
To be blunt, I don't know of anyone who doesn't fall in that category (except me)
