Just change your ways, you could leave for a bit if you think that will make people forget (dont announce it) but I'm sure that if you stop whatever it was you were doing (i have no idea who you are) it will be fine. Be nice!
A quick suggestion I have is to never post in the off topic sections. Don't risk it. You have other websites for stuff unrelated to Blockland. Use the Blockland Forums for Blockland!
Even if you dont fix your issues, I'm pretty sure you're going to be fine. This community is small, and doesn't have much of a presence outside of this website. Even if someone were to search you up and harass you like Freek implied, they will surely be considered a horrible individual by the community, and you could probably start legal action against them. Just cheer up! It's not the end of the world dude! :)
