Please explain to me what is going on. Who is giving out these bans, why and for what?

And whom do we need to talk to in order to get this fixed?

This whole situation is getting ridiculous.

But I second Andrew's solution. You have already posted WIP's in that thread, so that requirement is fullfilled. And I see nothing wrong with you submitting your entry by proxy now.

Hopefully, though, we can get this fixed before the challenge is over.
