Check out this web site it has a list of all the bots and shows which ones adhere to the max post age.....use only those with max age of 3.5 if you don't want to be hammered by the cat, I always wait for bots that have a profitable bid....they will show up as green and I try for those with a 5 minute window before the payout. It doesn't take long to catch on. If you wait long enough a profitable opportunity will come around. I liked your photo of the boat in the water.

You can use as many bots as you want.
