do whatever is equivalent in "strength" to a captcha.

let people edit things. make logs of all 'delete tag from module' 
operations - i doubt there will be many such operations.

give the community the benefit of the doubt - it'll take care of itself 
(i.e. if enough people come in and one made a mistake, someone else will 
fix it).

a drop-down will be problematic because people will want to create new 
tags (and that should be allowed for everyone).

let people edit tags, e.g. in case someone accidentally wrote a tag with 
a spelling mistake.

you could give a drop-down of common tags, and a text entry field. 
people will look things up in the list, or type the tag by name.

translate all letters to lower-case (or first capital the rest lower) 
and you're done with case sensitivity problems.
