Personally my opinion (not as a mod)
TF is not the only place where banks get the info, X is another big one.
Abhishek is the leader of such things so he should get the blame. He shares 4 tricks with us and then goes and informs 2 loopholes with bank and ask them to fix it. That's not a great thing. By doing so definitely people will curse him.
Others who are trying to be abhishek atleast are not directly informing the banks about these loopholes.
Where is the how to maximize rewards section? People who don't know that should know where it is.
