Trying to log in to website with a smurf-linked or suspended account fails with a cryptic error message

[StanczakDominik]

We have a pasta like this on the Discord:

Getting an Internal Server Error on the game website is usually a result of one of one of the following issues:

• You may be suspended. Ensure that isn't the case by searching for your nickname in in https://discord.com/channels/549281623154229250/774771372579880980.
• You may be trying to log in as a smurf-linked alt account. Try clearing your cookies or switching your browser. Also ensure you're logging in with the email/password combo for your original/main account, or an account you've explicitly gotten an exception for. Double-check this with the moderation team. Alt accounts are not allowed, try $text altaccount to learn why.

Please provide the username and email you're trying to log in with if these do not resolve your issue.

We should really have at least a better error message there! Something like "Report to the moderation on Discord, link here, #open-ticket channel, to figure out this issue.". If you figure out why this happens, I can optimize the error message :)
