What do you mean it is too much? Is there any exact times of claiming that can related into banning out account? I believe that if they have time to do it manually that means they will claim it of course. Last time if I still got time, I can make up to 12-16 hours per day which is pretty high too but there is nothing happened with my account. So may be you can give us some regulations on claiming amount per day
Giving regulations would be the same as giving instructions to the botters as how to avoid detection. It's not as simple as the number of times in a day, a few people are being blocked because they match the same pattern a very large botnet was using.
