I don't know. I run a SaaS that allows free user signup and significantly more than 50% of my daily signups are just signup "spam", without any visible motivation for doing so. The user name or information doesn't show up anywhere publicly and there is no inherent value in having a free user account. I've implemented some basic countermeasures (dummy form fields which reject the submission) which wasn't enough. I've added reCaptcha, and I'm still getting 50% spam signups from working (!) gmail addresses, meaning someone is able to receive emails on these. The majority of these are from places like India, Bangladesh, Vietnam, etc. I don't event want to know what my site would look like without my own countermeasures + reCaptcha + if it was a service where a user account has any kind of "value"...

Is there a particular problem if someone signs up for an account on your system and doesn't use it? Is such an account using a lot of resources?

  Well, you can't use raw signup numbers as a tracker of how well you are doing?

  Blocking others from signing up or using the username they'd prefer. For example, the bad actor could spam the registration with valid email addresses and depending on how your system handles registration it could either send validation emails to those addresses or block the person that owns the address from signing up.

  It doesn't use up too many resources, but I still don't like having more than 50% of the user database be essentially spam. If you ever want to sell your company you want to have somewhat accurate numbers of actual user registrations. Ever since I realised the extent of the issue I have become very doubtful about reported user counts from startups. In our case the only reason we've realised this is spam is because we annotate signups with GeoIP and also allow users to fill in a name and title which will then be something like "find escorts in Chennai" and the signup will be from India etc. If you only look at the email addresses all you'll see are many gmail addresses with western names, so you might be fooled into thinking that all of these are legitimate users.

    Is it possible that the emails are real, non-spammers and the spammers are abusing your registration form to send a short message entered in the name field to those emails like this person described? https://news.ycombinator.com/item?id=36446532 https://news.ycombinator.com/item?id=36446532
