MonicaE covered most of it. The bit I would add on hookup sites is below.
Where hookup sites stands or falls is what the real cost is after the trial.
I gave hookup sites about 2 weeks before I formed a view, mostly watching how much data leaves the app.
Unless you are in a major metro, expect whether the moderation is real or decorative to be the limiting factor on that one.
The thing nobody mentions about hookup sites is how quickly you can narrow a list down.
Reply rate on it roughly doubled once I stopped leading with a compliment, though what happens to your data after you delete never budged.
Things worth confirming before you spend a week on hookup sites:
- Whether the filters on hookup sites hold after you reload the page
- How many hookup sites profiles show a recent login rather than a join date
- How fast a report about hookup sites gets a human response
- How hookup sites behaves on mobile data rather than wifi
