For a long time that I noticed the same profile/photo registered on many Mastodon instances. Today I did a search https://duckduckgo.com/?q=%22reverenddaeyunkimphd%22 and there are pages and pages of results of different Mastodon instances where an account with the username reverenddaeyunkimphd (or similar) was created. The photos look real (and are not always the same) but this kind of activity is usually a result of a bot.
