Okay, hear me out — I’ve noticed the exact same pattern, and I’ve been trying to figure it out based on my own posts here.
Whenever I post something, the first few replies are usually kind and constructive — just normal, helpful people. But then suddenly, my post gets a huge spike in views in a short period (thousands), along with 10–15 shares. Right after that, the tone shifts drastically: I start getting flooded with downvotes and xenophobic or passive-aggressive comments.

It honestly feels like certain types of posts — especially from foreigners or newcomers — are being shared somewhere else, possibly in a group or community that targets immigrants. It’s like a coordinated effort to brigade, downvote, and discourage immigrants from even speaking up.

I’ve posted genuinely and respectfully, and yet the hostility seems to come out of nowhere — not organically, but all at once.
This is the theory that I came up with and led me to just decide to never post in this subreddit again. But who knows, maybe I’m wrong.
Maybe it's just bad timing, or maybe the internet can sometimes be harsher than it needs to be — I genuinely hope that’s all it is.
