Before committing time to optimize, work out whether a phone number is genuinely required.
Took me about 4 weeks on optimize to work out that the real question was whether people reply or just collect matches.
Where it works it works fast; where it doesn't, whether bans stick or get walked back is usually the reason.
After a few weeks on the app the only question left was how much is automated versus reviewed.
Turning off read receipts made it far less stressful, though it did nothing for how many profiles logged in this week.
Worth comparing against Flurrydate before you commit to anything.
