Ideas for my Defence Pure?

Backstory:
- I originally started this account to see if I could get a level 3 trained to 40 defence (all other stats 1) for absolutely free (Using a few trust seeking trainers)
- It only took 2 people to bot it up to 40 defence (I was amazed, 2k hp/hr at chickens)
- This account was level 17 with rune, and was awesome to go on and mess around (when I was bored)
- I then decided to get membership on it and get the defence soul-warsed to 70. (Sythe mod Jimmy did a great job =D)
- I myself botted hunter to the mid-70s, giving me 2 mill.
- When membership ran out, I used the account to watch fights in bounty worlds. When I was attacked for my god armor, the attackers usually gave up (I was level 25), except for mages - who I was an easy target for.
- I tried selling this account, but did't get any legit offers.
- Because mages pissed me off, I spent 800k on 37 prayer, and I was never bothered again (I am now level 30).

What should I do next?
Keep in mind, I would prefer not to get members for this account again.

First off, I'd just like to say, well put together background, it was easy to read and understand unlike every other person on this site that can't write a sentence.

Anyhow...

If I were you.. And didn't want to add members but do something with the account.. I'd probably get some mining levels to gain some easy money (60 for the mining guild - or mine at lumby swamp) Also I'd probably raise my fishing and cooking level, even though it would take the longest time in f2p, there's really nothing that interesting to do. Or actually... Mine ores and smith items, raise you're smithing level if you have the time to do so.

 

Use it to make cash by mining.

 

@ Siinep - good idea, level 30 defnerd skiller =D.
@ wspn - calm down son xD

 

I would just mine, good money and easy skill, not much in F2P anyway
