Flyposting around Wood Green

There’s currently an insane amount of flyposting between Wood Green and Turnpike Lane. 99% seems to be by the SWP, and is all over bus stops, street furniture and pretty much any vertical surface. They are almost impossible to remove, which means that TfL and the council have to waste time and money getting them professionally removed. If any councillors are reading this, please advise on what you’re doing to remedy this.
