Never used Kik, but a lot of social media is not pleasant to use anonymously.
Sometimes they want a persistent trackable identity for you, which means you may need to rent some SMS service or just accounts directly, usually with coins you mixed, just to register an account. If it's UDP or if they block Tor IPs, you may also need to pay for some VPN (client ran in a VM), but that makes you pseudonymous instead of anonymous (if VPN goes after Tor). You may even need to "sticky" the outgoing IP or at least country for some services like Discord. Using third party clients may also help avoid some annoyances. There are various free ways to do this if you don't want to pay, but expect more pain, and a lot more tries needed to register and avoid being banned.
