In that case, many positive feedback must be withdrawn which has been posted before the change.

I'm not changing feedback that was correct according to the "rules" when I left it.

I have added a positive feedback on Royse777, because he had created two pool and donated some amounts into the pool pot. Is my positive feedback correct on that case?

I wouldn't worry about it too much. You're not on DT, and if you believe it was correct when you left it, you should still be able to stand behind your feedback now.
The accuracy of the feedback is like your "Trust business card". Based on this, other members can include (or exclude) you on their Trust list (see my Trust list viewer), which may or may not mean you'll end up on DT at some point.
