In this question

Possible small mistakes in Springer's *Linear Algebraic Groups*

the question was modified by a formally different user (probably the same person with guest login). Since the modification has additions, and since we cannot be really sure the user is the same, shouldn't the modification be rejected?

Normally, yes. Substantial unauthorized additions to other users' posts should be reverted.

However, the two users here are clearly controlled by the same person -- they have the same gravatar. No action is necessary.
