Fully kiked in every conceivable way.

I don't know much about it But I'm sure posting things publicly isn't a good idea

you don't wanna be Racist or antisemit

It's owned by Facebook. It's a data mining tool. You are the product.

If you have a business then free marketing, but other than that a complete waste of time
