How to limit spam through cheating?

Question

Search Engine Optimization

in analytics, this site bot-traffic.xyz got 1000 entries. when switching to it, it redirects to the site https://www.gammatraffic.com/?utm_source=2140
, as I understand it, it will pour traffic to the site from different channels, so blocking only bot-traffic.xyz through htaccess does not make sense?
How to block all such sites at once, or at least all sources that https://www.gammatraffic.com uses ?

Answer 1
