Are clothing ads/companies who have overweight models or models with self harm scars glorifying bad habits?

I have started to see a rise in the amount of clothing (more specifically: lingerie) ads I get on facebook. A lot of them feature models who are overweight, who have self harm scars, who have tattoos, or who have stretchmarks or other things that you wouldn’t cosmetically see in more “mainstream” clothing companies.

The controversy tends to be around overweight models and models with self harm scars. Is it all that bad to truly show all body types, including scars and such, in clothing ads?

I will give my opinion on this after I hear a few responses.
