My own view of an Ask Ubuntu user whose participation is mostly in making minor changes (in this case tag edits) is that we already have mechanisms in place to deal with such occurrences.
I borrow heavily from MSO and Braiam's excellent answer to say that there are two paths to follow:
- Look at each one of the edits in isolation and decide whether to approve the edit, improve the edit or reject the edit. This is basic to editing work across SE and needs no modification in this case
- If there is an emerging pattern of poor edits from a particular user the system may very well catch this; if not flag for Elected Mod attention: we have tools to deal with this.
As a third point I would encourage some patience with users who are perhaps still working out where they can best contribute to Ask Ubuntu.
Some will end up becoming great editors, some will ask great questions, some will create incredible answers,
some will become great tag editors, and a very small number will become great all rounders.
But in the beginning there may be some flailing around that ordinarily should respond to gentle guidance.
