to the same host enough tiles, they will not be able to post the same link again.
Additionally, the site will flag all their previous posts with links as spam and they will
be instantly hidden via the auto hide workflow.
The suggest_username method showed up on codeclimate
so I thought I'd give it some love and make it more readable.
In the process removed trailing whitespaces and had to fix a
terrible spelling error :)
I noticed a few assertions of the has_many type were missing.
Also added a couple of specs which were testing in one direction only.
Just tipping my toes in discourse hope this helps a little.
* rename `User#password_required` to `User#password_required!`
* emails with "i" @ something are a special case as well
* get rid of `self.` and returns where possible
* prefer "unless a" instead of "if !a"
* `unread_notifications` without manually iterating
* introduce `User#moderator?`
* introduce `TrustLevel#valid_key?`, `TrustLevel#compare`, and
`TrustLevel#level_key`
