I made a video but it was taken up entirely by a post looking like this: https://imgur.com/a/1fwT94c
This isn't a big deal because these serious tags are uncommon, but still a small annoyance.
So I fixed it!
In threads that are marked 'serious', there is an automatic stickied mod post. ex. (shorturl.at/I1346). My changes will skip any automatically stickied comments, so they won't make it into the final Video.
Python was giving errors with TRUE as a bool, so I changed it to a string. Giving an undefined name returned a different error than I put in the except, so I edited it and ran some tests which were successful. I will work on implementing something to detect if the subreddit exists and if it includes anything (e.g. special characters) which cannot be in subreddit names.
