| A long time ago I was into what I called "aggressive content syndication" and I wrote a script that (over the course of two months) made several thousand users on an active developer's forum that didn't require email verification to make an account. I made a lot of effort to make believable profiles for the users, they had first and last names randomly chosen out of a database and profile pics too, though I made no effort to match the pics with the name of the user (e.g. nationality, gender, etc.) I had the users randomly upvote stories so if you looked at the upvote profile of the users it would look pretty normal. However when I finished a blog post I would have the system choose maybe 20-50 users to upvote my post and my post would go right to the top and usually get a large number of what I called "volunteer" upvotes. I lost the database that had the users in a hard drive crash so that was the end of that project. Note adding users at a high rate (usually many per second) is one of the more efficient ways to crash a web site because the users table in the database is frequently very active. ---- Generally people like to spam links into forums and any place where it is possible to insert links and personally I don't believe it matters much if the links are "nofollow" or not. Note it is more of a hassle to do this on a site that supports email verification, I used to set up highly interactive qmail servers that could do things like that but all the sign up emails would be on a limited number of domains that would stick out. I think the pro spammers have methods of creating large numbers of accounts at places like Google and Yahoo which are a great choice if you don't want your email addresses to stick out too much. |
I would of thought these 'spammers' would of given up because of verification, but it seems to continue despite many of accounts not being verified yet, perhaps they think they can verify later (which makes me think a TTL on verification emails is important) or that was an oversight completely on their end.
