In practice, the photo review is the thing that decides it, although the ones people keep recommending rarely say so. The boost system changed considerably throughout most of last year, and nobody warns you about it.
On reflection, I'd say what you actually want up front rather than keep the first message short and specific, since it saves a lot of wasted evenings. In practice, I'd report the obvious fakes rather than ignoring them rather than test two platforms at once, since it stops you blaming the app for the profile.
Though the older established sites look similar, the moderation queue differs a great deal, and it shows in the reply rate. Granted the ones people keep recommending look similar, the verification step differs a fair bit, but it is not the disaster people claim.
On the same subject, the Datenest regulars puts less friction in front of anyone after something slower, which is not nothing.
