What's most ironic about the real name policy on Facebook is that they've removed accounts or forced people to use fake names by classifying their real names as fake.
Yeah, things similar to this definitely happen. Anecdotally, I have a friend with the last name "Name." This was years ago, but when he first created a Facebook account, he had to enter his last name as "Namé." I think he eventually had it changed back by contacting support.
Really depends on your interests. I frequent several programming language/platform specific and photography subs, plus r/mechanicalkeyboards, and several from my local area.
Reddit's multisub feature makes grouping them easy (so I visit six places instead of 40).
The ones I frequent include financialindependence, headphones, coffee, mealprepsunday, running, bicycling. They all tend to cater to their audience fairly well.
