Hello. I don't understand #1, on #2 I don't think that need answer.
#3:
We have bot protection. But as you understand bots not interested in be blocked by server protection so they creating bypass. You won't see protection that will forever blocking bots and bots dev won't be able to make bypass. Also new version of bot protection will be only after 2.0, we don't have enough people to focus on such big tasks at same time. If we will start working on bot protection right now - it will delay 2.0.
