This user joined today and added links to 7 questions all with the same text. I don't know if the site is legit or not, but I don't think this is behavior we should support or encourage.
I imagine the possibility where users sign up just to post links of varying quality and overwhelm the site. This isn't a good thing.
What should be done with his link spamming?
What action should we take with dealing with these questions? Here are a few ideas:
Require a minimum of 200 rep to post links, comments, etc
Lock the posts and prevent new answers
Mark the questions for deletion.
Here are some sample questions that were List-like (asking for links). On most SE sites, these types of list questions would be marked as off topic, but as Bitcoin matures we may adopt that policy as well.
