In response to our inquiries, Rockstar confirmed that the bans did come about as a result of the FiveM mod, and that it does in fact violate their policies. "The FiveM project is an unauthorized alternate multiplayer service that contains code designed to facilitate piracy," Rockstar said in a statement. "Our policy on such violations of our terms of service are clear, and the individuals involved in its creation have had their Social Club accounts suspended."

It's not known whether the suspensions will be permanent, but Qaisjp said yesterday that he hoped to get in touch with the studio today in order to clarify the situation. In the meantime, while he also insisted that the use of FiveM will not lead to bans as it is strictly a single-player mod, his suspension would seem to rather obviously contradict that position. Consider yourself cautioned.
