BigQuery keeps adding useless data. What we truly need is common crawl data then we can check specific site on our own. Or wait, BigQuery simply can't handle common crawl size dataset in their public service! Otherwise there is no reason to not add it, maybe it puts their search engine/ad business in geoparady. Is there any other Google public dataset BigQuery like platform? Where their direct search engine/ad platform interests don't get in way of Common Crawl like data searching/indexing?
