I agree that "Wolfies" is childish and unprofessional and should be replaced with either Wolfram Research or WRI. Posts on this site should either use the official name or a commonly used abbreviation (like WRI or SE, even though that might be unofficial) for any company's name (not just WRI), and silly names (like Micro$oft) should be replaced.
Just to be clear, I'm making a distinction between "Wolfies" (childish/unprofessional) and "WRI" or "Wolfram Research". I don't think one needs to edit "WRI" to "Wolfram Research" (although, it is fine if that happened in the context of a more substantial edit).
As for this post, I have now edited it and left a comment for the user asking them to not use silly names in future. If the user rolls it back again, then please raise a moderator flag to let us know and we'll lock it.
In general, I think it's good if the community leaves a comment to educate the user and edits the post if it is necessary, but it shouldn't get into an edit war. If you see a back and forth on an issue, then please flag it immediately for moderator attention (and do not make any further edits).
