From personal experience I haven't received one ban while using RuneMate since my registration date. While I'm still a relatively new user, I usually have two accounts going when possible using similar bots. The breaking system is very useful, and is highly recommended. I personally just use the bots to get my stats up rather than gold farming, so I generally take 30 to 80 minute breaks and give the account a 24 hour break period if possible to cool off.
Both of my accounts are almost to 99 Mining, and Crafting. As long as you're using a bot that is frequently updated and has a good developer behind it, RuneMate is definitely the place to be. Plus I would rather "pay per usage" rather than buying a $25 to $100 licensed bot where the risk of it going out dated anytime is blah, considering I want to bot long term for my own leisure.
