making the slides hours before deadline is a horrible experience
Well, horrible is relative. I mostly spoke at (semi-)academic conferences where a) people don't really care about the way your slides look b) it's mostly to demonstrate things that don't work well spoken aloud, like formulas and diagrams c) you already have a conference paper written by the point you need slides, so you can reuse parts of it for the slides.
It may be a good idea to write a "conference paper" even if it's not a part of the process, since it can help you plan the speech, and you can also reuse it as a blog post.
For further actions, you may consider blocking this person and/or reporting abuse
