Declining Friend invitation

That solves so many problems.

And creates many more. Then SE has to police what addons are sanctioned.

What I'd like to see...
#1. Spam auto-filter: One person blacklists, everyone with the addon blacklists the same user for one day. Downside: False positives.
#2. Friend/Guild spam invite auto-filter: Same as above
#3. One-button-report: Where a screenshot is sent to SE, or a two-step report where the user is reported for something non-spam, and auto fills in the server, zone, user selected, etc.

Not really. You just limit what the API is capable of accessing. There's no need to approve or deny every individual addon.

If an addon comes along that does something degenerate that you didn't think of, you just modify the API so that it doesn't work anymore. For an example of this see Blizzard's response to an addon that projected textures on the ground. They just changed the API so it could no longer determine which direction the camera was facing.. boom problem solved.
