Valid traffic filtering out, spam traffic filtering in.
We're noticing some really odd traffic on our site via Google Analytics from countries where we don't have an office or users. We've set the permissions for this site so that only people from our domain can access but that appears to not be the case. We're seeing a lot of traffic from Russia and other countries where we do not have offices.
Also, this is the second most popular language that visitors to the site are using: "Secret.Google.com You are invited! Enter only with this ticket URL. Copy it. Vote for Trump!". Seems very suspicious to say the least. Was there a hack on Google Analytics or our site in particular? Trying to find out. Any help would be greatly appreciated. Thanks.
