Automated Giveaway Entry

Just curious as to what SteamGifts' stance is on people who are blatantly automating the entering of giveaways. I had stocked up almost 100 keys which I've been giving away over the course of a few days and I've noticed on multiple occasions situations like this:

Where it's painfully obvious the person may not even be visiting the site at all, but is just automating entries to keep his points below 300. Should I be reporting these people or is it my own problem and I should just blacklist them?

Edit: Some people seem to have missed the key information in the screenshot. I'm not referring to the fact the user has copy pasted the same comment. In two occasions, the user has opened three different giveaways and pasted the same response all three times in less than a second. This is not realisticly possible.
