User peepee drinker is obsessed with me after declining their advances

This user is against fujo rights, so I denied their online edating proposal, they recently told me some proactive things like to "oil up big daddy" and some other very concerning stuff, I told them no repeatedly but now they keep responding to everything I post with comments that they know will turn me on- in hopes that I'll finally accept their advances, how to tell them to fvk off respectfully?
