The original Titanfall is still up and kicking on Respawn Entertainment's servers, and we know this because players are having an issue there. A number of players have been getting trolled by a specific hacker in the servers of the first game, where a player going by the name Atomic Bomb has been running scripts against them, bringing up a "Too many Proxies for Datatable DT_BasePlayer" error and booting them out of the match. You can watch a video of it happening here.
Respawn has obviously had their eyes elsewhere for a while dealing with all things Apex Legends, and so the complaints to their boards as well as complaints to EA have kinda fallen by the wayside. You can see where complaints have mounted up on PCGamesN. While Titanfall may be low on the priority list with less than 100 people on their servers at any given moment, a troll is a troll. Hopefully, with more public attention being put on it, someone will get around to banning this player.
