They are not honest about their free tier. If you start engaging, they lock your ability to search for others and force you to pay before they unlock it again. The website says "Upgrade to premium or wait until start of next month to regain access". But when next month comes... still no access. I reached out to support and they said I should sign up for the premium account, and provide them my billing info and they'll give "14 days free". Yea... no thanks!
