Filing this as a bug, feel free to change to support if not the case.
Over at Stonehearth we had a user post a log directly as text in the editor, and was able to submit it. The post exceeds the maximum length allowed significantly, as I tried to edit the post to surround the log in a code block but was not allowed. The post in question was originally here and moved to here where I converted it to a Pastebin link.
The error received stated:
Body is limited to 32000 characters; you entered 2459079.
If it helps troubleshoot, this post likely went through the approval queue as the user is new and we currently have the first 2 posts from each user go into the queue.
