If I buy a good amount on a new fresh account as I haven't made one yet, will I be banned as it would be obvious rmt from their perspective.

Yes

it would be obvious from any perspective
enjoy jail

Depends on how you use the account I have alts that aren't nearly good stats that I personally trade billions back in forth in rs3, to trade with the ge, if caught trading for real money you could be banned, fg is not real money just another game currency.

It’s safe to assume RS3 has different detection systems, but OP stated it’s a fresh account so it basically has the highest risk of detection in OSRS.
Also for rs the real world trading rule states it just has to be an act of exchanging anything outside of RuneScape. It doesn’t have to be vs real money to break the rules

They are both the same company yes osrs has system set in like when the 3rd age axe was released and in the ge was only marketed at 32k and a guy sold it for 3.6B his account got flagged and banned and they were max accounts.

Same company, but both games run on vastly different game engines, so they have to have different systems to flag suspicious behavior. Not sure what example you’re speaking of but there are a lot of incidents where false ban waves go out on OSRS and the only way they get unbanned is through a Reddit thread.

Your quite right, regardless must own stocks in reddit to reply to you threw them? It's money not social media.
