We’ve turned into a Hive, things are getting serious.

Only Goliath from the Bible was three meters tall, and even then, it's most likely just a fairy tale.

about some citizen of the Russian Empire who was three meters tall due to a hormonal imbalance.

Are you talking about Makhno? I've read about him. He was probably taller than 2.5 meters, but definitely not 3 meters.

Getting back to the question of being three meters tall. As I said, the maximum height of people I have EVER seen was about 210 cm. That's just the absolute maximum. I've never seen anyone in real life who was even 220 cm tall. And I've seen quite a few people. And you guys think I could even become that tall? Are you crazy?
