I went to put in an outlet with charging ports and found this monstrosity behind the wall plate. The box is filled with expanding foam, I'm guessing as some kind of support? Then painted all over. I scraped it all out, put in outlet spacers and its much better. I think there's foam around the box too, but I'm not gonna worry about that (yet).
Now I get to spend next weekend replacing all the outlets in the house just in case there's any more sketchy "fixes" ๐ซ
After cleaning and replacing:
I do not understand why people do this. It takes literally ten seconds to put a piece of tape over it. You can even do it as you go!
I'm too lazy for all that. I pop the cover with a power screwdriver. Masking tape's expensive these days!
