I have no idea which is more prevalent, but fully agree that the idea the problems are limited just to the applicants deceiving unsuspecting sponsors is obviously false.
And as a parallel note: the pressure to approve more/faster/better (from perspective of the applicants and sponsors) is constant and unending; everyone is insulted that the possibility could even EXIST that they are being deceived or are themselves guilty of deceiving their partner. Or indeed that both are working together to deceive.
We /mostly/ give the benefit of the doubt here on the board (and I mostly think that's the correct stance). But that doesn't mean eveyrone's innocent.
It's VERY rare here that anyone admits that IRCC denied their application - but were actually right. And of course those doing the deceiving or outright misrepresenting admit it - when they're called on it, they usually stop posting, or otherwise divert attention.
I do remember one case of a prominent poster (a couple of years ago) who was OUTRAGED when his spousal application was refused. Perhaps six months later came back and admitted that IRCC had saved him a world of trouble, because his erstwhile partner was a confirmed fraudster. I don't recall the poster's handle and don't want to call someone specific out, but the huge red flag waving in the wind was that they had no photos because the partner had a 'social anxiety problem' about being photographed (or something like that, supposedly with doctor's notes or something).
Anyway the specifics are not important, the point is just that we never here about the cases avoided.
There are abusers, there are fraudsters. Unfortunately, one and the other don't usually meet until the couple is reunited. That is a risk of having a relationship/marriage with someone from a country where it's difficult to obtain a visa from Canada.
That poster should consider himself blessed.
