And what about men who are harassed in that way too? It did, and still does, happen, would it make the news if it was a male TV sleb accusing a female sleb of sexual harassment? I'd bet my house it wouldn't.
Why have his accusers waited x amount of years to go public with things? Why didn't they go public when nothing was done when it was first reported, if it was?
I'm not defending him, until something more serious comes out (if it does), then its just banter that adults should deal with there and then, not go running to the press years later.
He is guilty of coming across as a first class bell-end though, something I've thought for years.
Haven't these various reasons already been answered in previous posts

Plenty of people reported Savile and Al Fayed at the time, not just to employers but also to the police / authorities, nothing happened.
Some people may have gone to the press but don't for a minute think they automatically jump on any story just because someone makes a claim, they weigh up how many papers they think they can sell and then decide if it's a real story or a non story, sometimes things also sit on the back burner until there is sufficient weight behind multiple claims or it's a slow news day
Do you think people shouldn't have come forward about Savile and Al Fayed until after their death

Many people did but others didn't until after they died and these started saying something once they realised that actually they weren't the only ones it happened to and now they perhaps may actually be believed instead of being shamed

Wallace doesn't appear to be on the same scale as Savile or Al Fayed (from what we know so far) but as more and more people come forward it does show a clear pattern and history over a long time frame.
OK so i'll agree some of this is just cheeky chappie harmless banter but how far do you push it until it's unacceptable

A comment with lot's of people around IMO isn't as bad as it's less personal and the fact others are around doesn't make it threatening etc whereas if it's said one to one it's got a different perspective.
For example perhaps in the studio there's talk about what someone's cooking and the woman says something about it being a plum pudding with honey glaze.
If Gregg says to the whole crowd that he likes the sound of that and is rather partial to having his plums sugared then i'd take it as a bit of cheeky banter.
If on the other hand he waits until later when the woman is isolated and she's on her own with him and starts dropping comments about would she like to sugar his plums or see his sugared plums etc then that's a totally different scenario
Initial reports were about comments
It then moves onto touching and engineering situations where he has to brush past people etc
Then taking advantage of situations where the woman is isolated and can't get away such as in a car together
Then we have a situation where he engineers an early morning meeting at his place and exposes himself, again the woman was isolated
Some of these situations may have simply occurred however he's clearly engineered others and also taken advantage of situations where women were isolated or sought to isolate them, sorry but this is all classic tactics used by abusers and is in some part predatory
