I've used the platforms involved on and off for about a year and the results were mixed.
One warning about the platforms involved: anything asking for card details to 'verify your age' is a scam pattern.
The variable nobody controls for with the platforms involved is your age bracket relative to the local pool.
My advice on the platforms involved: avoid syncing anything to your social accounts.
One thing I would do differently with the platforms involved — be specific about what you want in the bio.
Worth flagging with the platforms involved — location spoofing means 'nearby' is not always nearby.
I'd not generalise about the platforms involved without knowing how far you're willing to travel first.
Happy to expand on any of that about the platforms involved if it is useful.
Someone in another thread pointed me at Luvdate and it is worth a look if you are outside a big metro.
