Scripters need to test their script in order to get a functional script. in order to test a script, the scripter needs:
An account
Stats required for the script
the requirements of a script can be quite high, so if a scripter needs an account to test it on, the account will be at risk since it's logged into a bot client + running a script
Now here's my idea. Tell me if it's impossible, not likely, or just stupid.
OSbot private server
An exact copy from OSRS, without modifications.
You can test your scripts all you want without getting banned
You can set your own stats (example: 63 hunter for a red chin script)
Not only will this reduce the bans, throwing away a potentially good account, it will also not require time to train the skills. 63 hunter can take a while to train, and if you bot it, you will have a chance of getting banned along the way
Adding to the benefits, a scripter can design a script that he otherwise couldn't make. a script with high requirements, example: Zulrah. There are a lot of other scripts that can be made with high requirements.
You could also test your script and go for a 100-hour proggy, without any chance of getting banned
server only accesable by scripters / staff obviously
