Well now that was interesting, but it really doesn't surprise me all that much. Let's face it, there are creeps all around us, what a shame right? There's always those few bad apples that spoil it for the rest of us.
One day I was just tooling around on steemit and came across a post about dporn. I was shocked then nervous, my grandkids use the platform from time to time and I just thought this type of stuff has no place on the forum. I know it would take some doing to get access, but kids are smart and tech stuff is easy for them to figure out. It's a click here a click there...I don't know but you get my drift.
I like your idea of changing profile pix and background setting to keep your site fresh. Nice going.
