I'm seeing an increasing number of people failing include a reason behind their tag alias or implication suggestions, with many of us having to remind them to do so.
I feel that it is counterproductive and serves only as spam, rather than giving a legitimate suggestion that everybody can discuss on.
I would suggest making it a requirement to have something in the "Reason" box so that you can't submit an empty proposal.
Consistently failing to do so would be grounds for Abuse of Site Tools and Spamming/Trolling.
