Yes I have a sand crab script for sale.
I botted a high lvl main using it.
Ban rates are low with private scripts when compared to public scripts.
But there is always a chance of a ban with any type of botting.
1. Reply to a thread asking for a scan. Use Virustotal to do it yourself.
2. Create threads related to merchanting (e.g. selling scripts, methods, etc) under any circumstance.
3. Create "which bot should I use/get" threads, without seeing other similar threads, and the resources provided (such as the search function on this site).
4. Create "Am I safe, Will I get banned, Is X safe to bot yet" threads. There are far too many factors to put into consideration with bans for someone to give you an accurate answer to this.
5. Create threads requesting a luring partner. Those belong >>here<<.
6. Create threads post account trades, even free accounts. This is not allowed in the Runescape section, as they are likely hacked accounts. 7. Create threads related to the advertisement of free or paid scripts.
