> Instead of just doing "fact checking" in form of "our data says it doesn't" its much more effective to address the original claim and expose the tricks used to give the impression that people are dying of heart attack after vaccination. It not only builds trust and reason but also makes people smart for understanding what's going on instead of feeling dumber than the "experts" who tell them the "truth".

This is in fact (no pun) what every fact checker I've ever consulted actually does. I assume a lot of people just read the conclusive "Lie"/"Truth", and don't bother with the paragraphs of reasoning and sources they're basing the conclusion on. If there are faults with sourcing evidence, logic, or anything in between, that's where the issue is, but the concept is fine.
