I actually tried it! For the keyword "scam" - that and nothing else - the first big-G result which relates to crypto was indeed from Bitcointalk: page 5. The page was BTT's "Scam Accusations" board.
For "pump and dump", the first crypto-related listing is also on page 5: ""Wolves of Bitcoin" Figured Out a Nice Little Pump-And-Dump Scheme." It's from Gawker's "Valley Wag." The next one, on page 6, is from Coin Telegraph. On page 7, there's the "Crypto Pump Group" - which certainly stick out from all the others. There are a couple more that are crypto-related on pages 8, 9 and 10, but nothing from Bitcointalk.
But Google does have the keyword "pump and dump bitcoin" as one of its eight suggestions, or "Searches related to pump and dump."
