Can owning a bot for Runescape get you banned even if you do not use it?
This is not likely; the rules refer specifically to using a bot,
and besides, there is really no way for RuneScape to detect that
you HAVE a bot, if you don't use it.
Can you get blocked from runescape for using epic bot?
With every bot there is a risk. Epic Bot is one of the best and
safest bots available for Runescape. I have run Epic Bot for days
at a time and not been banned, so your outlook is good.
