The answer at https://academia.stackexchange.com/a/182163/15446 is a copy/paste from https://www.modernintimacy.com/13-tips-for-how-to-heal-from-a-toxic-relationship/ (as noted in the comments by @Nobody).
I was confused on what to do (let's assume that the content of the answer is fine in itself)
- downvote? → I do not think so because the answer is fine (per assumption), it is the behavior of the author that is not
- flag? → not sure for what
- edit to add "source : https://..." ? → This sounds best for me, though it does not address the issue
- edit to add "OP: provide your sources: http//..." ? → this is an answer, not education about authoring
