RE: Is the Broken Tag Problem ever going to Be fixed I just wasted another $6 SBD because of this issue!

The Steemit dev team just closed the issue to prevent users from using 5 tags: https://github.com/steemit/steemit.com/issues/918

I have no control over their release process, so I can't make any guarantees - but I expect they will have it deployed to the site soon. They usually deploy releases at least once a week.

The larger fix (to actually make it work with 5 tags) is being worked on here. I don't have an ETA for that, but they are working on it.

Regarding the first tag being the category, I have not heard them having plans to change that. At a blockchain level - moving a post from one category to another I believe is a big deal, so I don't know if it will be something they ever implement. Best advise is to proof before you promote. If you find an issue, you can always erase the post and re-post it with the correct category.

[edit] Regarding refunds - unfortunately no. The site is in beta, so it is "use at your own risk". They try to prevent and resolve issues as much as possible, but there is no guarantee that everything will work 100%.
