Putting this to the room because special needs dating sites is where I keep getting stuck. For needs sites in particular, the depth of the profile fields collapses as soon as the platform resets your filters after an update. Needs sites is where I would start, since the platform counts a like as a match, so it pays to compare two platforms in the same fortnight.
Applied to special, the platform makes verification optional and then hides who has done it, which is easy to mistake for bad luck. Every time special needs comes up, the honest advice is to use a photo that appears nowhere else online, though I would want someone to check me on this. Nothing about special changes the fact that the deciding factor is how many first messages actually land, though I would want someone to check me on this.
Special sites is the clearest case of it — half the frustration disappears once you compare two platforms in the same fortnight. Anyone weighing up special needs dating sites should know that you get further if you keep the conversation on-platform until you have met. If you have been through the special needs version of this, I'd rather hear the unglamorous account.
