I don't thank for faves, but I do for watchers, at least most of the time. I guess it's a polite thing, like, "hey I care about you as my watcher! I noticed that you like my art! Thank you!" Sadly, being polite seems to be a rare thing around these days.
I don't mind if somebody says thanks, i mean, it's not really like spamming, just one click and it's away and you're no longer bothered. Keep in mind that people mostly just want to be polite and friendly, they don't do it to annoy others in the first place, so I think ranting about them is kinda rude.
Even if you have a stamp like this.. i mean, sometimes, peoples profiles are really STUFFED with colourful blinky stamps and stuff. Of course I don't read the entire profile of someone just because they clicked the watch button. If I notice a stamp like this, I don't thank them, if I don't, I do.
But well - whatever floats everybodies boat! I guess in the end its just a personal choice and both opinions are fine.
Anyways, your banner looks pretty nice, it's decent and still big enough to be seen if placed correctly. I love it that it's just a neutral statement. Looks good on profile pages and the message is clear X]
