Hi Overthet0p - no, I wouldn't worry about the URL shortener at all. Remember that spam score doesn't indicate whether something is necessarily spam in Google's eyes - it just tries to show features that are correlated with things we've seen Google penalize/ban. So, a Spam Score of 9/17 means that we saw ~72% of sites with that many triggers get penalties/bans in Google. But, that also means 28% of sites we saw with 9/17 flags had no penalties. If you've manually checked the site and feel it's not a problem, changes are it's fine!
