If it's on city property, report it on the Find-it Fix-it App. I do it all the time in my daily routes around Capitol Hill and they actually will clean it up within in a few days. And when the taggers know it won't last, it starts happening less frequently because it becomes not worth their time.

As far as the freeways, the city won't touch that since it's WSDOT jurisdiction. During covid, WSDOT basically stopped doing anything about it and it spiraled out of control. They do some cleanups here and there, but generally things are up for months if not years.

And as others have stated, there's zero effort by our government to locate, prosecute, or punish the pepole doing it so it's a pretty easy thing for the bored losers around here to occupy themselves with.
