Seconding what Natalie Pierce said, with one caveat about international dating sites.
What separates the site from the rest of the field is whether the recommendations improve with use.
Took me about 5 weeks on international dating sites to work out that the real question was whether a reported account really disappears.
If you are only browsing, it is fine. The moment whether it thins out after the first week matters, it changes.
The reason I stopped recommending some of these is how much of the base is genuinely looking.
Someone in another thread pointed me at Datebie if you want a smaller pool and it was a fair shout.
