sorry for all that "input error"-spam
The CAT tipping bot has only been running for 2 days and is still in testing.
Two facepalms on my end here:
1 - forgot to ignore root posts, the bot shouldn't even have responded here
2 - the invalid input routine had a pesky little punctuation error in the code which caused the task to not get removed after the reply and the bot restarting 10 minutes later.
Both problems are fixed now, sorry for the hassle.
