Ignore generic avatars from Slack #310

Open auscompgeek opened 5 years ago

auscompgeek commented 5 years ago

Potentially terrible feature request, but here goes anyway.

Slack now has very unimaginative fallback user images - they all look like this, but with different colours:

Slack default avatar

I personally feel Riot's fallback avatar generation is more useful, but opinions may differ here. :man_shrugging:

This is a request to ignore the default avatars when fetching from Gravatar (i.e. iff the avatar URL is Gravatar, and we get the default, ignore it).

Do you have examples of what we could use to detect the default? We would also want to be able to unset avatars if they changed to a default one.

The only way I can think of is to check whether it's a Gravatar URL, and change the d query parameter (or remove it and check whether the hash of the returned image is the same as the Gravatar logo?).
