Is Moz's rank checker driving referals (and bounces) in my analytics?

[10516VT116300]

I see 200+ referral visits per month from "rank-checker.online" and they all bounce with one second session durations.  Are these bounces hurting my SEO?  They are definitely distorting my referral metrics.  Can I block them somehow?

This is usually spam. The data showing in your Analytics is not real, in fact it is not a bot or a user and will not affect your SEO at all.

The idea of this is that a spammy entry is placed into your google analytics readings to fool you into thinking that the bounces are real. You then follow the link to see what it's about which in turn brings traffic to the spam site.
