Nothing is safe, just take the proper precautions to limit your chances of getting banned.

can they detect me botting without monitoring my movements and time online, can they detect that game is not run on original client?

 

I'm pretty sure the whole client thing is a rumor, it might even be against the law.

 

Just take breaks while you bot (Account manager) and act like a normal player now and then.

 

No one logs onto RS everyday and trains for 13 hours straight, same skill, same spot, same movements for two weeks straight.

 

Do u think i will be okay if i bot in rogues den for like 3 hours a day maybe and also play legit?

 

Yeah, I think you should be good.

Botting is never safe, although just buy a fresh lvl 3 for like 1.2m and then bot the fuck out of a skill, you should (at least I do) make your money back and a profit. Like I suicide bot, got over 5m so far. Paid 1.2m for an acc. 3.8m profit.

Nope, dangerous as always.

Just use the break for 30-45 mins after 2 hours and you'll be fine, got a 13 hour run with 30 min break (20 min variation) every 120 mins last night at hill giants and no problems whatsoever. Just be smart, I wont be going back to hillies for a day or two, which is the smartest thing you could do.
