I've been saying this for a long time but stealth can be safe for a few months but jagex will always find another way to detect it purely off the client you are using. Mirror can only be detected from your character in game being bot like.
I have got 20 99's with mirror, and the only bans I have ever got were from stealth.
Been using mirror for a while now.
Moderate breaks.
Got probably 20 99's over the course of 2 years.
Never been banned.
Mirror doesn't work well on mac apple silicon but it allows me to rest my accounts.
