I think these bots are very primitive and only one phrase can be written. The more you create giveaways, the more often you see the same people with the same phrase in each. What's funnier is that sometimes I can meet newbies who think this is how it should be done and write it by hand every time because they see it everywhere in giveaways :) The problem is that it is difficult to prove a bot and report, you need some clear evidence. But here at SG they at least fight against such giveaways, for example, the author will not receive a single point for this one.
