Suggestion: word blacklist

I was wondering if it is possible to add a "word blacklist" to the app.

I usually swipe for typing, and I commit mistakes frequently, so the app "learns" and suggest me this mistakes. I know I can remove a word from the prediction bar, but as I repeat that error, after a time it appears again in the prediction bar.

So I think it would be usefull to add a function to tell SwiftKey which word I don't want to see suggested again (i.e: tge for the).

Thanks!
