Is it worth starting up on an old account of mine I found which has 99 mining as a skill and nothing else - lol?

As long as you have fun playing the game? That's the only thing that matters.

amethyst mining is fairly afk and can be 300k gp/hour
if you let the account run in the background thats not bad imo

Looks like I have several old shitty accounts that were previously banned for macroing.
one has 99 mining, another 99 fletching, another has like 92 hunting.
Seems pretty worthless

Check rs3 see if they have bank loot on them

no. Not worth playing this miserable game

This.
