This came up in an anon sub about how to disable pings from anon subverses so I'll just quote my text:
"When someone needs to say something to someone they should just say it openly or on a private message.
When it happens in an anon subverse no one can verify who they are talking and 99% of the time anon pings are shit posts anyway.
Maybe a good idea for Voat is to disable the pinging feature in anon subs entirely or implement an 8chan style of anonymity where anon users can still use a designator or a call sign in order to distinguish themselves to other anons"
This way anons can't harass random voaters under anonymity, but can still form an anon community by opting to choose a designator that other anons can ping. All of this can happen without the user ever having to share their real username.
