is there any way to remove the censoring?

In a Flash animation? I doubt it, unless you had access to the source files (and therefore were either the original author or a close associate)...

I'll be damned, it works. o.O I wasn't expecting that.

Looks like that doesn't work anymore without opening the file in a new tab first. Even after clicking on the image, Danbooru keyboard shortcuts took effect while typing "peach" – and that's why we've had to remove ach (and "achach") tags from this post five times in the last 7 years.
