I don't think he was necessarily in the wrong it was just horseplay and Chloe took it as such.
However, he needs to read situations better and be aware of his strength.

If they had a food fight with certain foods or if someone threw warm water at someone for example I think they would also be warned.
It was a health & safety warning more than anything else

When Chloe barged him it was in response to the shockings
Maybe BB should have a word with her and say you must accept actions that happen within a task but she was more at risk of injuring herself bouncing off Marc than of hurting him by barging him.

I am describing the describable

Putting your hands on someone who has not invited you to do so is an assault.

I haven't seen the episode yet, but Marc does go too far with his behaviour at times.

Ive not seen the video but it sounds like horseplay and BB just warned them from a health and safety standpoint , which is fair enough.
I saw nothing wrong with Chloe barging into Marc.
I see nothing wrong with Marc and Danny wrestling - so long as they dont let it get out of hand.

He does, but its alright because he's Marc. BB's golden boy, and for some reason that I can't fathom, the forum favourite.

I do wonder if a female would be half as popular if she acted the way Marc does, personally I don't think she would, she would be hated on here.

It is cases like this that create problems on here simply because Big Brother picks and chooses what is acceptable. Then again, it is the same in real life.
