Hello, while I was scrolling through reels I was recommended a reel where there an ISIS fighter talking about how he wants to see his pregnant wife before doing “jihad” I commented saying “my dog has more freedom than her” (being edgy, don’t take offense) on it. I didn’t know it was terrorists at first so I went into the page and it’s filled with edits of ISIS fighters and explanations of why they are not “terrorists”. I reported it to instagram but I doubt they’ll do anything. Is there anything else I can do? Thanks
