Blazing Flare queries

The add 3k everytime an opponent's monster is sent to the drop zone during the main phase, does it stack?
For example, I use it's soul blast effect to rid opponent's Gigantic Charger, then I call Berserk Dragon and use it's counter blast effect to destroy Blaster Blade, does Blazing Flare Dragon add 6000 or only 3000?

Can stack.

yesit does add another 3k as the conditions of the effect were met again
