There REALLY needs to be a way to let you block PMs from certain users

[Planetnamek]

For the last hour i've received a flood of PMs from SpiritBombTriumphant harassing me with pro-Trump garbage(all because I told him exactly how I felt about Diamond and Silk when he tried to promote them to me) and I was hoping that adding him to my "foe" list would mean I wouldn't have to see his PMs anymore, but apparently that only hides his forum posts. There seriously needs to be an option to be able to block PMs from a serial harasser like him as I can only imagine how bad things could get if someone who was say suicidal got repeatedly harassed by someone in PMs encouraging them to "Do it"(just using that as example BTW)

I'm posting this on here because i'm genuinely not sure how to handle something like this.
