Frequently uses the same red paint arrows and boxes to highlight things
Not sure what program they're using, but ShareX (arguably the best screenshot tool) has red colored arrows/boxes by default when drawing. I would not consider this a valid way of linking. mdayonliner seems to be using ShareX based on the arrow style, while S_Therapist seems to be using MS Paint to edit their photos.

Am ShareX userThanks for clarifying, but I still think the way they use them and boxes to highlight things are more than a coincidence, especially when you take into consideration everything else, though of course it's not unheard of and would mean little by itself. I also suspect he tried to throw in a few red herrings here and there by mixing some things up but it's hard to hide who you are fully and people can easily slip up (see hilari). The accusations in the op are probably a moot point now though seeing as he's been tagged for buying accounts.
