-# Proposal for ignoring invites
-
-## Problem
-
-There is currently no way to ignore an invite in Matrix without explicitly
-rejecting it and informing the inviter of the rejection. There are many social
-situations where a user may want to silently ignore the invite instead.
-
-The closest you can currently get is to ignore the user who sent the invite -
-but this will then ignore all activity from that user, which may not be
-desirable.
-
-## Solution
-
-Currently we support ignoring users by maintaining an `m.ignored_user_list` event in
-account_data, as per https://matrix.org/docs/spec/client_server/r0.5.0#id189.
-
-We could do also silently ignore rooms (including invites) with an equivalent
-`m.ignored_room_list` event, with precisely the same semantics but listing
-room IDs rather than user IDs.
-
-## Tradeoffs
-
- * We're limited to ~65KB worth of room IDs (although we could change the
-   limits for account_data 'events', given they're more freeform JSON than
-   events)
- * We waste initial sync bandwidth with account_data info for ignored rooms
-   which we may never care about ever again.
- * The list will grow unbounded over time (unless the user occasionally
-   unignores and explicitly rejects the invites), especially if invite spam
-   accelerates.
- * We could instead have a dedicated API for this:
-   * `PUT /user/{userId}/ignore/{txnId}`
-   * `PUT /rooms/{roomId}/ignore/{txnId}`
-   * `GET /user/{userId}/ignore`
-   * `GET /rooms/{roomId}/ignore`
-   * `GET /ignore` (for querying the current lists)
-   * ...and a custom block in `/sync` responses to synchronise ignore changes
-   * ...except it feels that yet another custom API & custom response block
-     is even more complicated and clunky than making account_data a bit more
-     flexible.
- * Alternatively, we could extend `/leave` with a `silent` parameter of some kind,
-   and rely on the invitee's HS to track these 'silent' leaves and ignore the
-   room on behalf of the invitee.  However, it may be nice to let the user track
-   ignored invites cross-client so they can undo if necessary, which account_data
-   gives us for free.  Plus semantically it seems a bit wrong to use `/leave`
-   to describe the act of ignoring an invite, when you're not actually leaving it.
