As some of you already noticed, when you click on a link to follow/block/mark as spam a user, you will have to confirm this action on the opening web page:

The reason we added this extra step is because of some users had antivirus software that were scanning their emails and checking the links in them. When those antivirus programs were visiting the links, they were causing the different actions to be taken. We couldn’t filter out the different antivirus programs, because they disguise themselves as normal users, therefore we had to add this extra step.

We would love to hear your ideas on how to deal with this without the extra step, but for now we will have to keep the extra step.
