I see there's a hidden hyperlink on his post.
Use
Report to moderator. In this case, because there's only one post with a spam link, I typed:
Hidden spam link.
For others, I've used:
Spambot. Hidden link in this post, more spam in other posts. I'm only reporting this one: please Nuke!
Or:
Spambot (hidden link). Nuke please.
That's hidden hyperlink isn't harm anyone
The harm is done by spambots that create many accounts to spam useless posts for backlinks.
The main reason why I proposed this because I've seen so many people trapped into phishing sites
I don't see how this can easily be abused to trick people into phishing. That's much easier by using a fake visible link:
google.com.
There was a time when every HTML link in the internet was blue underlined. Those were the days

But it was removed because it looks better without all the bling.
