(no title)

Sorry, might be that the title is a little bit inaccurate. However, the post indeed describes multiple cases, when attackers have stolen many BTC from the exchanges, because of the issue with a weak isolation level. Moreover, one of the exchanges was totally ruined because of that.

Well, then maybe write a blog post explaining exactly what happened here and submit that?

Because, even having re-read the article you linked, it does not support the conclusion that "[an] exchange[...] was totally ruined because of [weak isolation]" at all?

My post is a secondary research regarding potential issues with weak isolation levels. It includes a link [0] to an in-depth description of what happened to Flexcoin. Additionally, the post references another similar BTC attack [1] that exploited a "lost update" due to weak isolation levels.

The goal of the post is to highlight this problem, as cited research papers clearly demonstrate that such issues occur more frequently than commonly perceived.

Again, I'm sorry that the title might be misleading and you have expected a different content.
