I checked that the ingame and out-of-game official tools that they had in plain sight, just to be certain. Then again I'm fairly inexperienced myself so I didn't check everything there was to meseta pso2 explore as far as electronic options go (more for me to look up I suppose) If anything. . If you figure out how to take down these meseta sites, another will pop up in their location and continue running like nothing happened. Domains are inexpensive and it does not cost much to rent out a machine to host the website .
Even in the event that you could, or sega could, take down these websites, they would only make another. They've an unlimited supply of emails and bogus credentials to earn new characters, together with proxy or ip hiding software so no action can be obtained on the folks behind them. They're not scumbags, they're developers looking to get easy money utilizing virtual money, bot applications, and manipulation of documents.
Sega can not do anything legally to them for breaking ToS. A number of them probably do, but a few of them are valid (if you may call service which breaks tos that) business that just wish to cheap Phantasy Star Online 2 Meseta create cash by selling gold, and without a proof that any specific gold selling is stealing cc information and/or accounts you can't actually do much about it.
And this comes from somebody that knows both people that compose cheats and people who sell gold at mmos. There are both valid cheats and legitimate goldsellers, in addition to people who will make you get viruses and steal your credit card insted.
