So the maximum daily rate is 10+20+10x2+5x10+5x5+2x5+2x5 = 145.
Assuming someone is not abusing the system by creating many false accounts to get refer a friend and to get themselves liked by themselves…
You get a new member joining today is 20+10+10=40 points then it takes (240000-40)/145 = 1655 days = Saturday, April 2, 2022 to get to level 21, and yes such a new member would need to create 2 threads/day and each day the admins make one of those threads a sticky.
If someone does abuse the system and creates lots of false accounts and Anker does not spot this, then the 145/day points becomes 195/day so then it comes back down to Tuesday, February 2, 2021
