Hello,

I’ve recently discovered and started testing the Discourse webhook feature (I’m working to add support for it to the rbot IRC bot). I’ve enabled a webhook that triggers in all events, and one thing I’ve noticed is that even with no forum action I’m seeing periodic updates to the built-in groups (admin, moderators, staff, trust\_level\_\*, everyone) and users (-1, -2) being added to groups. I also periodically get notified about updates to categories, even if nothing was changed (manually). In case it matters, the Discourse instance is [the GPUSPH one](https://gpusph.discourse.group/), graciously hosted by Discourse itself.

I was wondering

1. why these events get triggered (they seem to be always the same) and
2. is there maybe a way to filter out these events specifically (leaving the same event classes active)?

(Sorry for the early post, misclick)
