Despite of the fancy domain name the basic structure of goliathsearch.com didn't cope with a sudden influx of spammers - and to be honest I wasn't in the mood to intervene in their activity rather observing what they are up to.
These spammers were very keen to pollute goliathsearch.com with all sorts of illegal pornographic keywords (some of them I didn't even understand, I had to look their meaning up) and they had a rather sophisticated way of approaching your site and they went through Cloudflare's "I am under attack" check like hot knife through butter. Clearly they were able to spoof pretty much anyone and advertisers they even paid for their clicks until someone manually banned the account at their end (so much for PPC advertising cost efficiency and their fancy BI tools).
At the end of the day the Web Search of Goliathsearch is disabled. Unlikely to come back alive again as it was before - still good option for a honeytrap site.
