Help! Somehow I have 3000 new followers.

Today in like a 12 hour period I suddenly have around 3000 new followers, and I have no idea how. I must be on someone's starter pack, and they must have a huge following.

In the meantime, I don't have the capacity to follow that many people back, my fingers will fall off.

Is there any way to follow all of them back at once? I googled it and blue sky says no, but I thought I would ask here if anyone knows an end runaround.

It's hard to believe I have over 5000 followers now. It's kind of overwhelming.

Thanks 🙏🏼
