If you are a couple and you receive a message by a single male, you can both ignore the chat request, block that person, and also there should be a flag icon that allows you to submit a report, you can file that report to the reddit system for harassment or whatever rule such user might be violating, and most of the times, their account WILL BE SUSPENDED. Even better, the new AI is catching ban evaders and its not only recognizing IPs, but also MAC addresses, so its becoming extremely hard for these ban evaders to create a new account and continue to harass others.
We also encourage you to block these users so they no longer have any way to reach you again. SIDENOTE: If a "couple/female/male" profile seems sus, IT IS SUS!!
