Yes. First of all, you can edit questions yourself to remove them as and when they occur, especially if there are only 1-2 questions.
Secondly, new users cannot use any tags outside the top 1000. So they can't add junk tags like "myself". There's only one question with that tag and it's from 2010 before I added that option.
For other tags I have options set up to automatically fix or "normalize" certain tags, like hgss
-> heartgold-soulsilver
or hm
-> hms
. It also removes common/useless words like the
, and
, help
, question
and so on.
Feel free to give me some more examples and I'll look at adding them to the options.
