My main concern is what should I do if I find post hard to read because of poor formatting? Should we accept or reject edits only intended to make question / answers easier to read without adding to, changing or removing original subject, I mean that if text in question or text in answer to question is, for example, written in single continuous stream of characters without line breaks (paragraphs) or any other visual hints that would make reading itself or finding place where you were when you decided to look out for some proofs or maybe test out what was suggested for you. What would be best way to approach such posts? Should I just ignore them because they just feel like TL;DR? Or should I try to make quick edit, without changing any contents, to improve readability? Should I flag them as low quality as they will be hard to read?
TL;DR:
Should I do anything if I find post badly formatted and too hard to read?
