I recommend you consider a "smaller" advertisement. Right now, it's 50% advertising, and 50% is the actual comment of what you're writing.
You're probably less likely to offend people with an "ad signature" if 90% of what you wrote is an actual comment, and 10% is a one-2 line small text ad (maybe small logo).
Since I feel your legitimate comment was used in an abusive way (simply to spam an advertisement on a dated post that still might gain some readership) I'm going to downvote it. But now you know why at least.
P.S. You're right on the typo, but unfortunately it's a paid out post, that I can no longer edit. The system will not let me..
