Nobody can make sure that their accounts have not risk to be banned ,Here I would like to share some  personal experiences
1. create accounts, when create the charater you can see many people who may have been built directly point to confirm, not to choose individual personalities, I am feding up to see  MONK , ugly to dead, that way  I may  blaze my impulse to report these accounts;
2. Grades, dont  mixed outside when got only lvl3, if you stroll outside with the low lever, you may easy to track by GM , especially on a large cargo of gold coins ; runescape items
3. Exchanges, when on the game will inevitably encounter some players inqure something from you, you are sometimes to be asked buying things , the best way is  ignoring  them,or just reply  "im sory" ;
4. Online, avoid   24-hour online,jagex likes to track these accounts; www.innicc.com
.when trade with others runescape money do ya guys both take off and bring if something ,shun giving or accepting stuffs or gold ;www.lotro100gold.com
there are so many skills, you have to practice a few more options, do not practice single skill, it is obvious to  seek excessive profits of money as a single and high lever
7. Consumption, you have to play RS for such a long time, so u must have  normal consumption records; dont just save gold;
8. Keys, although there is few intelligence auto, but now there is runescape accounts a semi-automatic button,it also bring some risk; www.viccol.com 
Ha ha. Perhaps I said many people are aware that you may not entirely know these, maybe you dont  take measures, I do only to share my experiences to new friends
