I was about to reply "nonono it's not a date rape joke" but then I realised that the word "violent" in "violent sexual abuse" means it actually could easily be taken as one. I only meant to joke about receiving unpleasant messages on a dating site, which is probably not fun, but I think is generally OK to joke about. On the other hand, date rape is not OK to joke about. I've changed "violent" to "aggressive", which I think keeps the same tone I was going for but removes the ambiguity.
