Yeah those stupid ads really annoy me. There are "ads" like those near me too but they're mostly "YARD SALE" signs that people are too lazy to take down.
So many people do it though. I guess they don't think they'll get caught. Here people put ads on the traffic light boxes. RIDOT just painted over them when they service the cabinet lol.
Here they are all for "Safe abortion" with a cellphone number to an illegal backyard quack. I rip them off if i see them. These charlatans will do it at any time, up to 9 months..... Sad is that the Govt clinics do it for free, with counselling and support, but only up to 3 months, after that they offer adoption.
