Ok let's say you suddenly become a sitewide mod
For a short answer, chaos. But in a long answer
After realizing you are a sitewide you would ban most people who would disagree with you or who hate you, you would also change rules of imgflip and probably post porn freely, you can also purge people's popularity and straight up call out on them for [insert bad reason] and they will perish from being liked/loved to a hated human being, plus the fact some underage children might accidentally stumble upon porn art I mentioned earlier and they will be traumatized, including a possible immigration to other sites like discord, 4chan, reddit, etc. etc. after that you would probably become an dictator upon not just msmg but the entire website itself under half 7 hours.
the point is, you'd make this site into another hellhole, other than 8chan, 4chan, Twitter, Tumblr, reddit and etc.
