Who punishes promiscuous women? Both women and men are prejudiced towards sexually-accessible women, but only women inflict costly punishment

https://www.sciencedaily.com/releases/2013/06/130603142237.htm

Across all female participants, women -- regardless of their own promiscuity -- viewed sexually permissive women more negatively on nine of ten friendship attributes, judging them more favorably only on their outgoingness. Permissive men only identified two measures, mate guarding and dislike of sexuality, where they favored less sexually active men as friends, showing no preference or favoring the more promiscuous men on the eight other variables; even more sexually modest men preferred the non-permissive potential friend in only half of all variables.

I do agree (without evidence) that slut shaming internet trolls are 99% men though, but women can easily brush them off.
