Not technically exactly a thread bumping bot, but I've used a similar method in the past on another forum(gaming). It's not necessarily because I didn't want to be active on my thread(as I was definitely active and was answering as much questions as I can), it's really just because I wanted my thread to be bumped to the top of the boards as frequently as possible(every 24-25hrs). Without using this method, I was only able to bump my thread mostly like 3-6 hours late due to random times of sleeping and due to me doing some other things. When you're doing a lot of stuff, even though simply bumping a thread sounds simple and easy enough, remembering to bump a thread at certain times every single day becomes a hassle.

So, yea. I'm with Lauda here. As long as it follows the 24 hour rule then it's fine for me.
