These VERY good reasons are.....
- Its fun at first.... and people say that its boring after u get to level 60 blah blah blah. Have they ever tried becoming a member. When you pay for it you are a member, not only do they get the other 2/3 of the map but everything that a non-member will pay loads for they can get for free.
- Suuuuure you can be reported, Suuuuuure your account can be banned, but its not really that hard not to, just follow the veyr simple rules
- Scaming is EASY AS HELL!!! People in runescape are compele dickheads! (mind my french) they ask you to transfer things from one account to another, so you just run off. Also the whole filter thing is a great pass scamming device... if you know how to use it. Because if you say suck it will come up as ****, so just say, " hey look the filter blocks your passoword when you say it ********, when all you are doing is pressing the * buttton, and gullibale noobs will belive you.
- the last reason is a good reason, there so so many skills to use, even non members have things like fishing, mining, smithing, cooking, crafting...... and because all skills can be leveled up to 99 it will take ages but will be rewarding in the long run
