You know, I wouldn’t think that most people couldn’t identify spam when they see it. However, I’ve been to enough blogs and seen enough spam even on those blogs where people seem to usually monitor what’s going on in their comments area.
Heck, I know spam is getting pretty sneaky. Sometimes it’s hard to tell a good comment from a spam comment. If you’re not paying attention a new spam comment will show up on an old post, which is why I recently talked about making some posts private.
Still, you must be vigilant in fighting the great spam battle. If you don’t, not only will the spammers win, but those savvy visitors of yours that see you can’t tell spam from the real thing might decide to stay away. So, let’s see if I can help you out in some fashion.
1. Watch out for insulting spam. There are obviously trolls whose job, so they feel, is to make everyone else’s life miserable. Insulting spam is usually pretty easy to determine, though; it’s never on topic.
2. Watch for spam that’s not on topic. Maybe I should have started with this one, but I’m bringing it up now. There is spam that looks pretty good and you might miss it because you don’t read to the end. If a comment starts out intentionally evasive, it’s probably going to continue being so, or else it will introduce something that makes no sense whatsoever.
3. Set your spam filter to move a comment with even one link in it to your spam folder. Sure, every once in awhile you’re going to get a legitimate post in there, but what I’ve seen most often is someone following up a post with a link in it with a second post saying “hey, my post didn’t show up”, or something to that effect. I hope everyone checks their spam folders.
4. One line comments. Unless you know the person, you should probably just delete all of these anyway. Keeping something that says “nice post” is an insult to your blog, and is most probably spam.
5. Check out the email addresses. Most people aren’t using Hotmail anymore, but even if they are, if the name before “@” doesn’t make sense it’s probably spam. If the name you’re given is of one sex but the name in the email address is of another sex, it’s probably spam.
7. Now spam can come in your name. That used to be an easy tell as well, but some of the more sophisticated spam can read who the author of the post is and add it to their comment.
8. If the comment is written to the “webmaster”, it’s spam. Who really uses the term “webmaster” anymore anyway?
9. If the post is in another language and you’ve only ever written in one language, it’s most probably spam. Back in the day I used to copy some of those messages into translation websites to see if it was saying anything pertinent; just scrap it and move on.
10. Finally, if you’re not sure, even with these tips, you can always test the waters by sending an email to the email address. Write a short post saying something like “just seeing if this email is valid before I allow the comment on my blog.” If you get a rejection back, or heck, if you get nothing back, consider it spam and kill it. Even if it’s not really spam, if the person on the other end doesn’t respond, then they probably had no intentions of coming back to your blog, in which case you didn’t need their comment anyway.
I hope that helps. Of course, if you have Akismet on your blog it will help even more.
