Invasions

StudioMoonTV (Czech Invasion)
Czechpocolypse by the YouTuber StudioMoonTV. He made a video about the MinecraftOnline server. Being created by a previously banned player, many new players from Czechia and Slovakia showed up with malicious intentions. This invasions started the trend of mass torch grief up on the raised walkways.
api448 & 
lemons222
Api448 and Lemons222 were both players who were banned but would come back for months to come with a vengeance. With the power of a VPN, and cheap/free alts, these two carried out highly strategic and devastating grief attacks on the server. Due to them both being overlapped almost perfectly with their attacks, it was believed they were the same person. Evidence suggests they were two separate people though. Their main targets were builds of those who they disliked before they were banned. Some of the targets are Spawn, BenjaminStad, player’s vaults, many warps, and of course, Snaketown, which was famously griefed over a dozen times.
Githis & EPU
A few months after the nightmare of api448 and lemons222, a player by the name Githis was banned who also came back with a vengeance. He started a group known simply as EPU, who made a [video directly attacking the server]. This group carried out coordinates griefs similar to api and lemons, mostly aimed at the same targets, ushering in a few more months of darkness. More bans occurred in this period because Githis used many alts to quickly spam something about having a ‘back door to the server’ or how ‘MCO is communist.’ Lemons likely partook in grief in this period as well.
FuzeIII (French Invasion)
Baguette language was a joke some players were making about a mass grief attack of French players routed from the video by FuzeIII

ZetaSSJ (Spanish Invasion)
On November 11th 2021, a Chilean YouTuber called 
ZetaSSJ uploaded a video premiere about MinecraftOnline to his 2.15 million subscriber channel. Not long after the premiere ended, the server was flooded with dozens of spanish-speaking players, reaching a player count of more than one hundred players and causing both drastic drops in tps and multiple server timeouts. Because ZetaSSJ clarified the strictness of the rules in his video, most of the new players did not join to grief but either simply play on the server or just to try and meet the YouTuber. The area Zeta built at was called El Reino Z, and the area attracted hundreds of his fans, creating what is probably the largest city in Freedonia besides spawn.
Fabo (German Invasion)
