Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 130 Stack Exchange communities.

I understand I can't put a bunch of links in my answer with <10 rep to prevent fake users spamming answers, but I can then comment on my own post and add as many links as I want.

It's nice that this workaround/exploit let me post a couple helpful tutorials to help someone learn something, but it seems like a loophole.

Am I missing something here?

Because you need a whole lot of reputation to post comments, and we all trust that you're not a spammer... ... ... right? –  BoltClock's a Unicorn Jan 10 '12 at 20:16
    
Note that you cannot add more that two external links in posts. (But any number of internal links you like.) –  Arjan Jan 10 '12 at 20:16

Links in comments are limited by the comment length limit. –  Andrew Barber Jan 10 '12 at 20:17

He's talking about comments on his own post; the comment-everywhere privilege doesn't apply. I think Andrew's right here. But what about multiple comments? –  Matthew Read Jan 10 '12 at 20:19

@BoltClock'saUnicorn right but if I WERE a spammer I could spam all I want in comments on my own posts –  Rembrandt Q. Einstein Jan 10 '12 at 20:25

+1 for the multiple links ;o) I had to check them all if they were different :-\ –  Laf Jan 10 '12 at 21:06

I don't think you're missing anything, that does seem like a loophole. It exists because two rules exist for different reasons.

  1. Users with < 10 rep are limited in the number of links (and images) they can post in one answer. You're right, this is to cut back on spam.

  2. You can always comment on your own posts. This helps cut back on the number of new users who post follow-up comments as answers. Commenting on your own posts is so commonly needed that it makes sense to let everyone do it. (You can only pollute your own posts with unnecessary comments when you have < 50 rep, so at least it's contained.)

I'm not sure if anyone has actually exploited this loophole to post spam. Flag it if you see it. If it gets to be a problem the loophole might get closed.

Indeed. I imagine that there's enough barrier in having to post a question, know that you can put multiple (or any) links in comments, and actually doing so that there's not a lot of upfront value for performing that check. –  Tim Stone Jan 10 '12 at 20:28
