I hate furrys and even created a instagram where I pretended to be a furry and trolled this guy from my school who is a furry.
That's actually bordering on being obsessive. Why did you you do all of that?
I just like upsetting them because they're ridiculous.
That seems unkind. It's not nice to pretend you are like other people just so you can embarrass them.
I also made a fake site where I sell fursuits to these people and now they are sending me a lot of money.
I hope you're not lying to them about having an actual suit to sell them. Accepting money under false pretenses like that is a crime that you could be charged with. I would advise you to refund any money and shut the site down.
