It's now been about a year and half since I offered my proposal to fight spam in the comments sections of online articles by allowing authors to selectively block comments from people based on their user profiles. So far, I have no evidence that Disqus has taken up this idea; as Alexanda Petri observed in a 2014 article on Christmas Creep, "It is almost as though writing about things on the Internet had no impact on them whatsoever."
But I can, at least, do something to help you with the more commonplace type of spam - the kind that regularly invades your inbox, displacing important messages about work and social engagements with offers to refinance your house, claim your foreign lottery winnings, or increase your penis size (regardless of whether you actually possess a house, a lottery ticket, or a penis).
My latest Money Crashers article is all about how to fight the scourge of spam. Although there's probably no force on earth that can stop every spam message from getting through, you can slow the flood down to a trickle by learning to recognize it (and ignore it) when you see it, taking steps to keep your e-mail address private, and training your spam filters to do their job better. You can also fight back directly by reporting spammers to the FTC (they can't stop them all, but they can penalize the worst offenders) and protecting your computer so they can't hijack it and put it to use in their nefarious schemes. As a bonus, I offer some tips on how to block unwanted texts and robocalls, too.
