Should a reaction be counted as a participation in a thread?

@gsouquet As discussed in the duplicate issue (now closed), the following interactions should be considered high signal and thus be part of the matching criteria for the "My threads" filter:

• Starting a thread
• Replying to a thread

Ideally we'd also consider mentions, but as you already pointed out that's not going to work at all for encrypted rooms, so we have dropped that requirement.

As for reactions, we consider those low signal/engagement, so those should be excluded. A proper follow/unfollow mechanism, planned for a future release, would allow users to selectively follow threads even if they haven't actively participated in them.
