You probs need to stablish some measurements against people willing to lag the server out from the inside (aka creating lag machines) I'd say just boot anyone doing so, anarchy shouldn't mean being allowed to mess with the server's integrity.
Otherwise I'll check it out, it running 1.14.4 means there shouldn't be too many people in or it would be unplayable very quickly, there is a reason most anarchy servers run 1.12.2
