Where to train f2p ? + worth?

I'm making an f2p account with 99 atk str def. I am using AutoFighterPro the name is very difficult to report + I am baby sitting it so not really possible to get banned ? Idk. Well just tell me where should I train it ? Currently it has 60 att 60 str 60 def. I cant do the strong hold of security as auto fighter pro sometimes fucks up in the doors, i dont know if its fixed now or not ;D so where shud i train in f2p ? and what is this account going to be worth after 99 att str def hp 1 prayer 1 summon

 

I used to do lesser demons in f2p but I needed food. Not sure, maybe try moss giants.

 

I've been running Auto Fighter Pro flawlessly in the Strong Hold. Give it another try at Flesh Crawlers and Zombies.

 

How about some red spiders? It's usually not crowded, and there's many of them so you can just keep on attacking.

 

Could always try ice giants if your defense level permits you.
