Luckily I never had all my eggs in Discord's basket, and thankfully so. I will remember this, and I know they are welcome to discriminate against Tor or any other traffic, but that just means they opt for lazy solutions and don't care about false positives. I host websites and online services (at a
much smaller scale than Discord, at that) and I know how people use Tor to abuse services. But, I also know that there's a comparable number of incidents coming from traditional ISPs, hosting ranges, dynamic home IP addresses, public proxies... you name it. This is extremely apparent in the form of E-mail SPAM.
I just believe that placing bans or flags on IP addresses is not the answer, and I will work on my own software and services with this ideology in mind. Ironically, Discord did have what I believe to be a stellar answer to guild moderation: invite links. They allowed a whitelisting model for private guilds, as well as varied forms of controlled access for more-public guilds. I'd like to see this kind of control everywhere.
