I've seen quite a number of campaigns coming out which malformatted Markdown (headings inlined in paragraph text due to lack of newlines) and spelling problems which could have been caught by a spellchecker.
I would suggest an improvement where the user setting up the campaign, can select some options to run their content through such tools as markdownlint and a spell checker (maybe more difficult because may need to autodetect - so probably best to use an external API), and if they come back with problems about the content, let the user correct until they're happy.
