Just as I write this, a user with $\sim$500 rep. has retagged 28 questions inactive by removing the tag differential-equations to leave only the tag pde. This has crowded the main page with already answered questions, and I find this very unnecessary and nocive for actually active questions. Aren't there any regulation as to editing that many questions , some as old as November '10? Shouldn't they be moderated by high rep users before getting bumped up? Is there any way this can be avoided in the future?
ADD 31 by now.
ADD Some examples of the edits. Red means removal; green addition. Black means unchanged.
