I have a youtube account and was once accused of stealing content from my own reddit account, which had identical usernames. Plus the reddit account had a link to the youtube channel and vice versa.
... but even tho it was a bit of a brain fart, I still appreciate that people are looking out for potential content thieves. I'm not even mad - I'd rather get a false positive every now and then instead of having my content stolen (again).
The photo is literally a screenshot of that tweet, just not in dark mode. Why on earth would it be from a word document?! Or was that addition purely so you could make your comment 42 words long? Like this one is.
Reminds me of the time I got into an argument on Twitter, and I asked someone for proof of something, and they sent me a screenshot of a Wordpad document. I said I was born in the afternoon, but not that afternoon.
I run a porn community and one of my posts got reported for being NSFW. On an NSFW community. On an NSFW instance. I don't know what they were expecting.
Personally I'd prefer a screenshot of a post than just a copy-paste of the post, easier to see the context, etc., and I'm also more aware that it's not the OP's take, but something they saw.
