I'm gonna show you how i used my fishbot, with minimum time, and mostly Safe!
Step 1:
Recruit yourself, make a new account for your bot.
-Upgrade with with cheap CDkeys (I used Randyrun) and Game time.
Step2:
You should now have a second account, and the x-53 Touring Rocket (Thats a extra)
Step3:
Level your character to lvl 10 (You should have RAF, so this should take about 1 hour mindless killing)
Step4:
Once you are lvl 10, you can go to Dalaran and fishbot yourself to 375 (I did this under the builiding wich stands with pillars in the water, stand on one of the pillars and noone would see you.) (I used Crap Away! addon To filter all useless crap, and only loot Sewer Rat (Another extra).
Step5:
You are now lvl 375 Fishing and can train yourself to go upto 450!
Now get your main on your x-53 Rocket allong with your second account (the lvl 10 with 375 fishing). Now fly your lvl 10 to Dragonblight to (Wowhead maps coordinates: 11,6-43, You can sit behind the waterfall on a rock, where noone can see you!
Step6: Set-up your Crap Away addon to only loot Dragonfin Angelfish, and Musselback Sculpin (These sell most on my server ofcourse there are more fish there).
Step7: Set-up your fishbot (With lures if needed) First you'll catch some junk caus your not 450 yet. Once your 450 youll catch all the gold.
My Results (Of 1 night fisbot):
35 Stacks of Musselback Sculpin
29 Stacks of Dragonfin Angelfish
(I got 6.4k for these stacks caus im a main supplier to a big guild, but usualy these fish sell for about 50g/stack)
Note:
Incase your thinking: Why would i spend money on upgrading a bot account? I think its better to purchase a money making machine, then a one time delivery of gold?
Goodluck! and Have Fun!
