Then, NexonNA just needs to require this on all newly created reports. They also need to connect each phone number to a specific account. If this account receives a ban, so does the phone number. This Maplestory 2 Mesos , once a bot account is prohibited, it will require a new telephone number to generate a new account. Phone numbers, while plentiful, are far far less abundant than ip addresses are.

It is trivial to get a new ip address, takes mere moments, but getting a new phone number is a lot more work, and also capital intensive. This places a huge barrier that only gets more successful over time (as more and more telephone numbers are blocked) against bot accounts. But it does not hamper legitimate gamers at all (because, frankly, if you've got a computer that could run MS you've got access to a phone of some sort ).

I know that there are a number of disadvantages, but I do not believe they are big enough to justify not implementing this method. The biggest drawback I can see is that a bot/meso farmer uses your phone number and has it banned until you try to make your account.

If that's the case, there might be a fairly intensive way to clear a phone number (it would have to be more intensive to be a successful ban). Either that or you're out of luck, however, the probability of that occurring anyhow are slim to none to start with.

Also, nexonNA could automatically ban phone numbers from all countries outside the serviced nations, thus making it harder for chinese meso farmers to work (they'd require a massive supply of American/canadian phone numbers and corresponding telephones on hand to create additional bots).
