Why aren't the ban messages including clear links pointing to what caused the ban as one would expect out of sanity? You are asking for people to appeal to some generic message.
Explained (quite recently) - too much extra work for the hundreds of automated accounts being banned...
So you run some sort of bot that automatically bans accounts and you don't even double check manually that it makes sense? If something is automated to auto-ban, then it can be automated to include what it caused it to autoban within the ban message as well.
What's too much work is spending years here, generating good content for the forum, making connections with people, then have your account banned because some bullshit automated bot ran by someone lazy enough to not quote reason of bans, then get sent into a weird ass looking email which theymos will never read, appealing something you don't know because there are no details. Unbeliable.
