It doesn't matter much (see what Vod wrote), however, he deleted the posts.
Just for the cases when it'll matter, next time make a capture of the "problematic" posts, for example you can use
https://archive.fo for that.
He was quick. Not active posting spam but also an alert member to remain safe. If he would have showed some smartness while making these posts, it would have benefited both the forum and that member. Some members think that their own interests are above that of forum. If someone has to succeed on a platform for long run, he has to ensure that his actions do not affect that medium negatively.
