> When the Lobsters algorithm said his account was too new to post a link, I thought I was vouching for and reviewing his project link by posting it myself.
I'm pretty sure this would be considered a normal vouching & introduction of a member to the site, if those members did not then repeatedly follow up your introduction with repeated self-promotion (including bonus violation of the spirit of the unseen domain policy). As someone inviting others to Lobsters, you were trusted with a small duty to introduce them to the site properly. For most of those you invited, you were both the person initially posting the invitee's relevant unseen domain and the inviter for that invitee. It's respectful there to warn new users of site policy that you don't expect them to know.
When I invited a friend to Lobsters a few months ago so they could post their cool new project there, I made sure to educate them about the self-promotion policy so that both they could continue to use the site and so that I didn't become a problem for the site.
As a Lobsters user, I think you could have avoided those spam flags with a less click-baity title and opening line of the body. “MIT CSG Memo 137 was the first CS publication to use the term "object-oriented"” would have been a better title, since you posted after the result was discovered.
