"H.P. Lovecraft was an American writer known for his contributions to the genre of weird fiction and horror. Here are a few notable quotes from his works:\n\n1. **From "The Call of Cthulhu"**:\n "The most merciful thing in the world, I think, is the inability of the human mind to correlate all its contents."\n\n2. **From "At the Mountains of Madness"**:\n "Yet there is nothing that I can do to clear my mind, for I am so deeply entrenched in the madness that I know no escape."\n\n3. **From "The Shadow Over Innsmouth"**:\n "I could not help feeling that they were evil things—mountains of madness whose farther slopes looked out over some accursed ultimate abyss."\n\n4. **From "The Dunwich Horror"**:\n "The thing we thought was a dead man turned out to be a living, protoplasmic horror from beyond the strange, dark stars."\n\nThese quotes capture Lovecraft's unique style, blending cosmic horror with a sense of dread and the unknown. If you need specific citations or further information on a particular work, feel free to ask!\n"

Hey @Grooty Welcome to the community!

Just a thought, are you filtering out the bot’s messages in your Slack trigger? There is an option called “Usernames or IDs to Ignore” which should help stop the infinite loop.
