~ The thing is most people are using google and they're trust the first to third domain since it's a popular sites, this forum has low traffic and people were interested in this forum because of Bitcoin or crypto, not crypto gambling.
We can't prevent this kind problem and most newbie getting end up being scammed, after that they will learn to search more deeply.
Maybe this is the case at the moment, but in the future I believe when someone searches for "crypto gambling" on Google, they will see bitcointalk in top results.
I just checked, and, for me at least, neither "crypto gambling" nor even "Bitcoin gambling" makes bitcointalk.org to appear in the first 3 pages. This will change, I'm sure, because the info one can find here is much more reliable than on some sites that take top positions currently.
