ex continues to stalk me ahould i do this?

we broke up over 2 years ago now he stalks my instagram with fake pages although i’m blocked from his. i only know that because i thought of messaging him to tell him to stop I know it’s him bc he’s told me he looks before, and he has an obsessive personality and was stalking his ex before me too while we were together. i don’t want him back and i’m worried about opening communication with him again bc we were trauma bonded should i tell him to stop or deal with the sex bots all over my page
