Um....
I seen lot of anti advertisers, but they are not all 100% percent prevent, and not even 50% .. like people can put spaces or remove dots :/
I remember the most succesfull way is to block numbers, but now people can't write numbers which is important in chat...
So I think this is best way to prevent advertisers .. :-
To block numbers if more than 6 numbers, because I don't think there is IPs that got less than 6 numbers, and even 7? Who got info whats least number digits for IPs in CS then provide it
Thanks, and hope it will be made
