How hard it is to understand that:Are you a minor? Just make a throwaway and keep it signed in
1. Not only minors hate age verification bullsh*t.
2. Creating and maintaining one more account (even if "throwaway") still increases your cogntive load in this case for little to no benefit.
3. When you are signed in, you are being tracked to a much greater extent then when you are not. Google account tracks you across all of their services meaning if you are signed in they will record your Youtube watching history and Google search history by default. If someone wanted to be anonymous because of the kind of games they play, why would they voluntarily give them info about what videos they like to watch and whatever other kinky sh*t they search on Google?
Blogspot has no excuse to ask for sign in to access adult stuff when Pornhub can perform the legal equivalent of age verification without asking you to sign in. People should just boycott any devs that are still using that and not having either their own site or some other sort of presence.
