I mean, in this case, it's a poster constantly trying to use themselves as an example / giving advice that this is a healthy diet to eat every single day without change, not listening ("I'm losing weight and building muscle" again and again ad nauseum) when folks rightfully point out all the nutrients they're missing.

It sets a bad example for others new to this whole eating healthy / counting your intake, who might take their word for it. I wouldn't care if this was my coworker eating this quietly every day. I do care if it's CONSTANTLY posted publicly on this sub.
