And people are trivial to go around. But, phone verification is much harder to get around. It can be as straightforward as replying to a text message, or receiving a phone call and going through an automated method (eg. "Punch on your pic to confirm that you are the cheap Maplestory 2 Mesos who created this account.") , so that nobody is excluded if they don't have a phone.
Afterward, NexonNA just needs to need this on all newly created reports. They also must tie each phone number to a particular account. This way, once a bot account is banned, it will require a new phone number to make a brand new account. Phone numbers, while plentiful, are far less plentiful than ip addresses are.
This places a massive barrier which only gets more effective over time (as an increasing number of telephone numbers are blocked) against bot accounts. But it doesn't hamper legitimate players at all (because, frankly, in case you've got a computer that can run MS you have access to a phone of any sort ).
I understand there are a number of disadvantages, but I don't believe they're large enough to justify not implementing this method. The biggest disadvantage I can see is a bot/meso farmer uses your contact number and gets it banned before you try to produce your account.
If that's the scenario, there might be a fairly intensive way to clear a telephone number (it would have to be more intensive to be a successful ban). Either that or you're out of luck, but the odds of that happening anyway are slim to none to begin with.
