My daughters and their friendship groups use TikTok (Private accounts - Sorry, Phil) and have great fun. The routines they do are perfect for their age group, but it has zero relevance to men in their 50s in terms of participating. A Dad can take pleasure in being shown what his children have created. A 50+ year old choosing to interact with them as some kind of peer is something completely different. Platforms like Snapchat where messages disappear, and the sender is alerted if a screenshot is taken, would appear to be a haven for an adult you wouldn't want trying to make a connection with your teenage children. I'm not saying that this applies to PS of course.
