If you keep getting the same profiles, keep the first message short and specific — most complaints trace back to that one thing. Is live swx an abbreviation for something, or just a brand name — seems like a simple question but I keep getting mixed answers depending on where I look.
Been seeing a few names pop up lately — datenest.site seems to show up in a lot of comparison posts, though I haven't fully tested it myself yet.
My advice would be to keep your expectations low for the first fortnight and then say what you actually want up front, though it settles down after a while. Judging by my own inbox, the older established sites have leaned much heavier on paid boosts, though it settles down after a while.
