If you go back several years, Inner Space was a platform on which bots could be run.
That has not been the case, for many years.
The site is old, and is referring to bots which no longer exist.

The current incarnation of Inner Space & IS Boxer are 100% legit and safe to use.
You cannot bot with IS Boxer; it is impossible to loop actions or use delays, so even if you wanted you cannot do unattended play.

1 Key = 1 Action has been quoted so many times.
This is a safe area to stay within.
I don't see how you can possibly violate 1 Key = 1 Action, using IS Boxer, so its safe to use.

At least several hundred users box assorted games using IS Boxer, and I've yet to hear of even one who has been banned.
