Ivan Shapovalov (@intelfx:intelfx.name) nuked his HS database and when it came back, he ended up with a corrupt matrix HQ. Leaving then rejoining doesn't help. Thousands of, "Event content has been tampered, redacting" in the logs.

So,
|
|
1) all re-joined rooms get affected;
|
|
2) this is not influenced by regenerating or retaining HS's signing keys on db nuke;
|
|
3) In fact, rooms "heal" themselves after some time. Exact conditions unknown, but each affected room got "healed" after a long enough conversation on that room (where "long enough" is not really defined, but exchanging one to three test messages didn't help).
