Same. Doing this is highly looked down upon, and tagging so many people to bring attention to your post to attract votes will definitely do the trick, but they're not all going to be UPvotes. Hopefully this is a lesson learned.
You should also be very wary of the tags you use on your posts and make sure each one is relative to your content. Tagging communities and including your post in categories it doesn't belong is also a good way of attracting unwanted attention.
