Snape, Obliviate, Neville?

I have a question for those far more conversant in the books than I:

I've noticed that several fanfic writers have chosen to point out 
that, in *their* Potterverse at any rate, Snape has an antipathy 
toward Obliviate.  Is there canon support for this?

Just wondering if there are implications in this re: Snape's behavior 
toward Neville.  I checked the archives, but may have missed an 
earlier post as I'm going to be late for work!
