Heh. Hmm... actually, the more I think about it, the more "frack" might be fine. Honestly, this is something that might need discussed
After all, I know Yosemite Sam did say "rackin' frackin' varmint" on several occasions. It might completely depend on context and how it's used. There's also the fact that each moderator thinks slightly differently -- what I find okay might be a complete travesty to someone else. Welcome to the small complications of a forum
If any other moderators want to chime in, that'd be great. Just know that if we edit a post, we're really not trying to be mean; it's part of our work, and we just want to make this place suitable for all our members and guests. Not all forums try to keep things age-appropriate, but we don't try to be like most other forums.
