My thanks are always sincere, it's you who are presuming they are not. And what's with all the bot insinuations? Yes, all of my comments are the same. However I can't be expected to write a different note for each of the several thousand giveaway I enter, I'm not that expressive. A simple thanks is sometimes enough.
If the creator expresses they do not wish to be thanked then I don't. If there are multiple giveaways per person at the time I thank them only once (xn).

I hope this is sufficient for you because I'm not continuing this conversation any further. Have a colorful day :)
