Getting too many spam traffic from a few sites

[lootmeup]

Getting spam traffic it isn't a new thing. Usually they are too small in size so we just create a filter in analytics to keep our metrics clear. But now the spam rate has increased exponentially. We even tried to contact the site owners of those sites. But they didn't even care to reply us.

Its happening right after Google started rolling its core algorithm last week. We use Cloudflare (paid option) as CDN. Some might say that they can povide any solution for this. To those who I say I have checked all of our options haven't found any solution to this particular problem.

Any kind of suggestion or tricks are much appreciated?!
