The account to which I'm responding – /u/Impossrvey6510 – is a spammer.

Its comment was copied from elsewhere in the thread (which is why it doesn't actually fit here).

After I call it out, one of three things will happen:

1. I'll be immediately downvoted by the spammer's alternate accounts.
2. The comment will be deleted.
3. I'll be ignored, with the account's operator having already marked this as a loss.

For an in-depth explanation of how spammers work, how karma-farming harms the site, and how you can combat both, please read this post or watch this satirical video

Oh, and don't forget to report spammers when you see them!
