True, we all know how these rating sites work but in my eyes AntiDolos is even worse because he presented himself here as someone who exposes scams while it looks like that is secondary thing to them and instead they are just another shitty rating site like ICObench that can't be trusted.
I don't know the whole history with AntiDolos, and I am not defending them at all, I only wrote my opinion based on OP post and images he posted.Maybe you know AntiDolos better as I hear he offered you to ''work'' with him before
I second this. It's a common practice, but only if you know you can't get a higher score.
Well you know how this things work better than me 
I am sure there are bunch of scammers in crypto who would do anything for money, all I asked from OP is to provide more evidence and I would gladly support him.
There is no such honest rating website. How would you think they get their business or even pay for the hosting and website maintainence?
I agree but only partially, ratings can be tricky especially if money is involved.For me best practice would be to add notice that you received payments from some service for listing or rating.
This is textbook extortion. Here is a draft of a bad review, pay me money and I will make it way better. As I said I don't care, but others will and did and will and did pay.
Textbook extortion would be if he continued to bully you with phone, email, telegram, etc asking for more money, even after you clearly told him NO.
