Last night I threw together a quick bot to post a random item from a text file in about 20 minutes.
Then I spent 3 hours going through the archive from my old LOL_Spam project at birdsite, pulling out jokes that are too dated or cringeworthy. (I'm hoping I didn't miss any. I was really tired by the end.)
This morning I modified the script to take a second file as a queue for new items.
So if you're interested in funny/odd spam subjects (and OK with swearing & lewdness), check out @LOLspam
