Joining Turbine and CCP as the only other companies to do anything effective about RMT in their games, Flying Lab has decided to suspend accounts for buying in-game gold:

This evening, Flying Lab Software staff issued a series of permanent bans as a result of gold selling activities by players of Pirates of the Burning Sea. Additionally, 24 hour bans were issued on multiple accounts found to have participated in the transfer of this illicit gold.

Please understand that we will investigate all reports of illicit transactions and we will following up with the appropriate disciplinary actions, which could include confiscation of the resources in question, and ultimately banning accounts that sell or buy these illicit resources.

This makes me happy like you would not believe. Although, I'd much rather see them just perma-flag the accounts as PvP, yarrr.
