The bots are on every server and if you haven't seen them you are just not in the right areas at the right time. I have characters on several servers, including Siren and Gilgamesh and there are tons of them. They have FC's. The archer bots typically turn in to spirit bonding bots. We all know the areas we see them at. Go to the Burning Wall, several will pop up at The npc for the BLM quests. Just follow the MSQ and you'll find them. Gathering bots haven't ceased either. Go to Little Solace and you will find 2-3 gathering bots that have been there for days, they will have one class to 15 and be lvl50 gatherers. It is absolutely terrible on every server. If you think your server is free of them, I'll make a character on your server and show you.
