From your a thread on this forum, I saw you are doing backlinks building in wrong way and maybe you also did other SEO techniques not right way and It's reason why your website hitted by this update
You have more important things on your website need to be improve, it needs time and your effort on your forum.
I think first you have to remove all that spamming stuff that consider you in spammer. And than after make some good and quality back-links which increases your back-link power. But remember only deal with that site which is good in the eyes of search engine.
Now that this update is related with Google, so we must try to analyze such links which have been detected by them as spam and then try to fix, remove them as soon as possible and avoid such ways in future. We can use Google link explorer for analyses.
The best thing I can tell you is analyze and disavow. Then start being smart with your link building. For instance, I take extra precautions likes using private proxies when setting up profiles. I also make sure that I use the same area on the profile that the IP is in. Im not sure if they detect multiple profiles being set up with an IP or not but I imagine they will in the future.
Also build a network of sites on different servers, if you are linking to your site from other site you built. Linking to a site on the same server will slap you.
There are so many things that could set off alarms at Google.
You just have to find out how REAL links are built and then artificially reverse engineer it.
