Yes..It was discussed in this forum before...but it seems it was suppressed later on....
Anyway, now it is becoming double sword thing...
If you share openly with anyone, people will downvote you and will blame you when it is gone...
Everyone wants that he will only know but others will not know...That is very difficult, I think impossible...as if you know it from an open forum, that means everybody else will know it and eventually it may go if banks get loss due to this...
