Well, in this story, the owner said that they DO scrape them off; but people keep putting them back on. I guess BP happened to see one before it was removed.
Maybe you should put it on your own property, instead of getting a company into trouble. Ever thought about a lawn sign?
Please, grow a pair. This has nothing to do with vandalism, look around at all the leftist messages that never get removed. This freaking out over a “sticker”is a result of the leftist getting a taste of their own medicine. See Alinsky’s Rules for Radicals #5.
