Don't suicide bot, waste of time. The only time I suicide is when it's a free skill (meaning no cash is spent except for things that are needed to start the skill eg. Woodcutting, Combat, Mining, etc.) and I just made the account.
One time I made an account and botted like 6 skills to 99 with 600m on it, I sold it for like $250 to my friend. Apparently he's been suiciding it since I sold it (2 years ago), and now he has like 16 99's, WTF.
Anyways Ontopic: I suggest if you DO suicide, do it on a fresh account, and on a free skill. Also start with free skills so you don't waste $6. If you do upgrade to member, buy it with the cash you've earned. It really sucks to get banned on your main or on an account with more than like 20m. Also transfer every time you reach like 10m. As much of a pain it is, in the end, having 200m from a banned account that could have been lost is worth it.
