Also I have a tip for fishing botting which I'm not sure where to put. Anyways,
I did tend to get my bags filled with 50% sealed crates/crap after 8 hours of botting which didn't please me too much. This resulting in alot of trash-fishing for the last hours of activity.

To avoid this I now usually split up the fish I know I'm going to fish like shown to only get fish, and not trash. If the bot gets trash, it won't be able to loot it resulting in a new throw and hopefully fish.
