As @misscrystal said, she almost certainly got a flag as well, hers just wouldn’t show up on your side. Hers would be taken seriously since she was clearly trying to break the rules, so when a human staff person gets to that one in queue, she may be banned outright. Staff is pretty active with that sort of thing, but the auto-flags allow for a list to build up so they know what to look at. I don’t think you’ll have much negative impact if any.
Edited to add - if you were the first person she sent that too, they wouldn’t have a way to catch it first since auto-flag words are sometimes innocent. Once she’s been flagged, there is a good chance they’ll put a stop to her intentions.
