It was mention it before by others and even by me - I guess you didn't try to check the previous pages with comments otherwise you will already know what you need to do to avoid the bad ending and will no need to ask!
In all honestly the creator missed a massive opportunity with this bad ending. There were so many clips that could have been used for certain paths that would have been a lot and I mean a lot more painful for the MC to watch while having the entire world see in the process.
For example if you are doing the bare minimum AKA keeping GG as resistant as possible, as well as not having MC go down the cuck path or basically just doing a standard none special play up to this point the original clip of GG sucking Jamal off would work perfectly.
However lets say if you had GG giving into Jamal's whims to the point where she the option to humiliate her son is open and she does it Brian could have used that clip instead. If the player chooses not to indulge but at the same time chooses not to refuse Jamal's next request Brian could have used the clip where Jamal uses the MC's mother as a toilet.
If the MC was engaged to Khalifa then Brian could use the clip where he took her virginity before she commits Suicide.
There are a couple of others I could think off that would have been a nasty gut punch to the MC however those would be depending on if the scenes I think are coming in the future will actually happen.
