Can you suggest an autoclicker (if it's not against the rules, of course, if it is I'm sorry, I didn't know). With the one I'm using I only get about 440 point with 25 click/s.
There are websites to check your autoclicker just google it.
Autoclickers are allowed as long as all they do is clicking, no automation allowed. But I've never heard of someone getting banned for breaking that rule unless they bragged about it.
