Hi!

Great question. In general, badges and achievements in GitHub Discussions are tied to the actions that earned them. Here’s how it typically works:

Answer Badges:
For badges like Galaxy Brain (for accepted answers), if the accepted status is removed from your answer (for example, if the question author unaccepts your answer), you might lose the badge if you no longer meet the requirement (e.g., you drop below the required number of accepted answers).

Contribution Badges:
If a badge is awarded for contributions (such as merged pull requests), and those PRs are later reverted or closed, the badge usually stays as long as the original contribution action (like a merged PR) is still counted. However, this can depend on the rules of the project or platform.

Event/Milestone Badges:
Badges given for participating in specific events or milestones are usually permanent and are not removed.
