"Your IP Address has been terminated due to Advertising"

I use Proton VPN, I logged in with my account and got the message "Your IP Address (146.70.174.70) has been terminated due to Advertising."
Someone must have done something wrong with this IP address. The problem is that I'm being punished even though I haven't done anything.

My account is very new, which could prove that this happened before I created it.

How can I get out of this ?

Thanks.
