This could be through scam promotions on Bitcointalk, Reddit, or any other social media sites, or maybe through Google ads, etc. Instead of just completely ignoring it, spend a few seconds reporting the scam site as to hopefully prevent potential victims from falling for these scams. Even if the difference to be made probably is just minuscule, it could make a difference.
Remember, it only takes a few seconds.
Reporting a scam site is a good idea but it does no good if the reports aren't acknowledge properly.
For the above mentioned websites:
How many reports are needed for a scam site to be taken down ?
If we report a site, what are the chances that it will be taken down ?
I also think when if a site getting down then they created a new one. So, it is better not to report only but to warn some person from the kind of scam on the site because they can create a new site but if a person totally don't know then they easily bait from the site so it means the problem was on the people who actually bite a bait.
