Thanks for the feedback! 
I don’t agree it’s discriminatory or ineffective for two reasons.
Firstly, GitHub users that have recently created accounts have very little to lose if they engage in trolling, as they could simply create a new account and move on. On the other hand, a 2 year minimum longevity means the user is likely invested some time in their account and built up some reputation, raising the accountability factor.
Secondly, one of the aims of the project is to add as little maintenance as possible on the owner side. By requiring some accountability we reduce the possiblity of getting spammy shoutouts and having the owners weed them out themselves, exposing them to potentially harmful messages and adding to their workload which is the opposite of what we’re trying to do.
Moderation is a possibility but it relies on community, which we don’t have at the moment, and is more complex. That being said, there is some support for a voting system on shoutouts, but thought it best to see if the accountability option works.
Thanks again!
