Can 410 links trigger a penalty?

[Blink-SEO]

Hi! This is a follow on question from my other post - http://moz.com/community/q/site-dropped-after-recovery.

As mentioned there, I've ad a manual penalty revoked for http://www.newyoubootcamp.com/. This came after the forum was hacked and some poor quality SEO was done. We've managed to clean a large amount of links, but ones such as http://about1.typepad.com/blog/2014/04/tweetdeck-to-launch-as-html5-web-app-now-accepting-beta-testers.html (anchor is "microsoft") are still being found and indexed.

My question is that although the forum is now 410'd, can these junk links still be causing any harm? A huge amount have been disavowed, and many others taken down after a manual outreach campaign, but still others are appearing. The site is performing poorly in search despite having a much better domain authority, driven by largely great links from national newspapers, than its competitors, as well as solid user metrics such as a bounce rate of 30% and few on-site issues. This makes me think it must be the link profile.

Any advice would be much appreciated.

Great. Also remember that the disavow tool only uses the latest list you send in, "Note: Uploading a new file will replace all previously uploaded ones." from: https://support.google.com/webmasters/answer/2648487, so make sure that the list you send in last is the most complete list you have.

In general, I try to get a site's referral traffic up if it's not a healthy percentage of their site's visits, so if the PR company is providing that as well via their placements then they're really doing well.  Cheers!

Thanks Ryan! The press has come in before and after the spam, they have a great PR who's got brilliant coverage.

When disavowing links, you can also disavow by domain, like: about1.typepad.com... This can help speed up the process in some cases.

The work you've done currently seems in order. 410 is fine to use per Cutts himself: http://searchenginewatch.com/sew/how-to/2340728/matt-cutts-on-how-google-handles-404-410-status-codes.

Has the press come before or after the problem with the spam?  It'd be nice to get a similar amount of press as link recency plays a part too.
