Well depends if you mean graffiti as 'people ruining derps' or graffiti as the whole other alternative culture that exists in in some part in a venn diagram overlap with urbex, which it also is. Core graffiti scene's name of the game is to have your tag seen in hard to reach places (ie the terms 'getting up' and 'all city'), with the 'higher leagues' of it always centred around trains, and there's a whole myriad of politics within that. It's hard to compare something like DDS's cause and modus operandi to people spraypainting stuff in derelict buildings. Writers that really live for their 'game' would get the creeps at the mere thought of being associated with people who go into abandoned buildings to paint big gaudy bits. Sure there are ruins that basically amount to legal 'street art' spots (Torrington, Loxley etc) and as an urban explorer one should be occupied with visiting superior localities anyway, but doing your 'piece' in an abandoned location like the control room pic Albino shared above (or even more controversially on the Burans) is neither cool nor core nor organic by anybody else's standards. Speaking of organic - then there's the third matter of kids being kids. Scallywags scribbling so and so is a cunt at their local derp that they go to to smash shit up and vape or whatever. Nobody's ever going to stop that unless the derp/mine whatever gets well secured, so, meh. Is what it is. But yes, bottom line, if there's graffiti in a derp, it means it gets a lot of footfall, and the appeal of it ought to wane.
