[Suggestion] Importing Block List from Steam to Blacklist on SG

probably already posted but i couldn't easily find it...

I would think it 'd be awesome if we could import our block list to SG as I often block people who have attempted to hack/spam/phish/scam me and i certainly wouldn't want any of the in my giveaways.
Perhaps make it an option in case some users use their block lists differently...
