I got a notification on Instagram that "Your support request from March 11 was just updated."
Not remembering what request I submitted, I clicked for details.
Apparently, I'd reported an account and they had officially banned the account in question. I kind of lol'ed at the fact that it took 9 months for this action to be taken...until I noticed that I'd originally submitted the request on March 11, 2017! It took nearly three years for someone to review the abuse report?!
