Asking ChatGPT to write a poem about 3 Yu-Gi-Oh cards :) #chatgpt #yugioh #poem

On the website I can select to follow a hashtag. But when I select to follow it, where can I then see all the hashtags I follow and where can I see the posts with the hashtags ? Do they end up in Home, Local, Federated timeline or somewhere else ?

Anyone knows why I see this lock on my profile ?
