I used to splash with an autoclicker by MurGee. You stop auto-retaliating after 20 minutes so I set it up to click every 17-23 minutes randomly. However, I thought that clicking inside the game into the same spot would be too suspicious, so I actually set it up to autoclick onto an on-screen keyboard left arrow key. The end result would be that my camera would rotate a little bit every 20 minutes and it would cause my character to keep autoretaliating and allow me to splash all night as I slept. It worked pretty well but in the end the exp was too slow so I switched to doing randomized auto-alching with the same program. You can download the autoclicker for free and then torrent the crack for it that's what I did.
