I try to assume good intentions, but at this point you seem to be simply trying to spread misinformation, and I don't know why.
The maximum number of rule sets is 50, not rules, as your own link clearly and unambiguously states.
The actual minimum (not maximum) number of supported rules is 30,000:

In reality, Chrome supports over 10x that. And UBOL doesn't even use/need the minimum, sticking to around 17,000.
