Adsense Rev Decreasing

My Adsense account was put on an ad limit, which I believe was some facebook traffic we were receiving and I cut that traffic off. Adsense finally lifted the ad limit about a week and a half a go and my regular traffic that has been going for years is still sending traffic but now we're getting 90% of the RPM's we used to. Revenue is 90% down and seems like its just a bit better than the ad limit revenue we were getting but not by much even after the lift.. any one experience this ?
