Make all photos censored until you open them
Guys keep sending me dick pics. I have it in my profile title and description both that I don't want unsolicited nudes, and accepts NSFW pics set to never. Guys still send unsolicited nudes, they don't read. Grindr has already shown that they don't bother persecuting these people because nothing has changed. Make all photos censored upon sending with a "click to open" button similar to Whisper chats. This way I have a chance to ask if the picture is a nude or a face pic and I'm not just getting blindsided with a random dick in my inbox. If you're worried about this making Grindr users pissy, then make it a feature that can be activated on my account. Don't make it a premium feature, because it's not about convenience or ease of use, it's about stopping sexual harassment.
