Spams resurfacing old topics, not current

Spamsters are picking old posts to dump their trash on, so old topics keep resurfacing lately.
I've been using the Report function... it makes the spam posts go away, at least for me, until I go back to the topic, sometimes.  Anyway, the admin cleans them up eventually.

 

Spammers on here are posting links that contain Malware and possible randsome ware , viruses . Please make note to report this to whomever it concerns and get the Moderators to be alert of this on these forums. Thank you :) 

I think they know already.
That's what spam does.
