"All I ask for is that everybody sticks together and we try to get ourselves enough points to make sure we're a Premier League team (next season)", he added.
After the game, Noble urged supporters to get behind the team in the weeks ahead.
West Ham fans could get their club relegated if the "aggressive" climate continues, ex-Hammers forward Sir Trevor Brooking said.
Sullivan was also hit in the face with a coin.
"I didn't see it myself but I did have that confirmed, which was part of the reason why the people in the directors' box had to go inside to save any more problems like that".
"That atmosphere must never be allowed to come back otherwise the club is in serious trouble".
It was a tumultuous end to a turbulent week that saw a protest march called off as West Ham fans groups turned on each other.
Gold's decision is quite strong and admirable, as it shows that he has the best interests of West Ham at heart. West Ham issued a statement after the match, pledging a "full and thorough investigation" into how events deteriorated to such a staggering extent, but Sullivan has already apportioned a degree of the blame.
Noble, 30, said of Brooking: "He probably felt the same as me walking off the pitch". A lot of the stewards on duty are stadium people and sometimes haven't had any experience of dealing with football crowds. It seems to me there's so much anger out there that it's not going to go away. I don't think there's any malice in players getting hold of them, they're just saying "come on, get off the pitch", a few of the players were trying to guide fans off the pitch.
If there hadn't been that neutral area between where the directors were sitting in the front row and the 300-400 - that's only an estimate by me - irate fans who were shouting at them, pointing at them and throwing things, I think someone could have been seriously hurt, in addition to that coin which was thrown at David Sullivan.
"It is not that I support the club, it is actually that I love the club".
