Performance guides are just a rather unfortunate thing to make here. Like once every other month some random dude just shows up and makes one of these as their first ever post. It happens often enough that people are really tired of seeing it
You often join threads talking about technical stuff. From your POV you're just trying to contribute in a meaningful way, but for others it sometimes seems like you're just trying to flex. I vaguely remember you also being called out in the past on giving misinformation which very quickly makes people lose faith in your posts.
I genuinely believe you have good intentions. The issue is you fail on the delivery.
Requires learning how to read the room better, how/when/why you participate in threads and how you structure your comments. Really that's just a general thing communicating anywhere. Both online and irl.
Also some people on TFTV are just gonna be mean regardless. Most of it is shitposting and trying to farm upfrags. Understandably, it's frustrating. Though if you genuinely try to do better, over time people see that effort and most will get off your back
Hope this helps
