Blackhat Does google do this!

traffic drop was not unexpected, according to ur graph, you got low traffic two days before the changes.

Google analytics, in any condition, donot affect the traffic (except that adding it increases loading time>negative effect).

Possibly some high pr website removed your backlink or your website was re analyzed by google bot for lower ranking.

Have u checked which keywords were getting u traffic, and are they still performing?

You should concentrate more on seo if you want to get search engine traffic.

Have you deleted meta tags?

in my opinion, removing adfly plugin might have been cause of this.
Have you checked ur outbound links for nofollow tags?

Coz if you r not using adfly, than all your outlinks might be leaking juice and hence giving u a low ranking.

well bro, there might a reason, i used to post alot in the forum before, now i have stopped posting at high frequency. only a thousand posts a day i think
Before was like 4-5k....
Could that be a reason...

Yea I would say that is the reason, your forum activity has drop, plus there is new panda update.
