I like them, but I hate them.
I LIKE them because I like getting thanks and little pictures on my wall.
I HATE them because there is no way to control or pin or really organize your wall. So any important announcement posts you make, such as hiatus, convention announcements or other things, get quickly pushed down by 'thx for sub HUGE PICTURE' posts.
This loathing came from me just having exceptionally bad years when it comes to family members and pets dying. Or my health acting up and making me bedridden. So when I go on hiatus to take a break to deal with death or my health I'll make an announcement as such. That's the time I usually look around for new comics to read and sub to. Which would fill my wall with 'THX' posts, push my announcement down and then get me people posting on my wall, pming me or finding me on other forms of social media with "WHY ARE YOU NOT UPDATING. UPDATE NOW' 'WHERE IS THIS WEEKS COMICS???' 'STOP BEING LAZY' "WHERE IS THE UPDATE???' 'ARE YOU STILL MAKING THIS COMIC??????????' harassment. Which I obviously don't need in my life at that moment in time considering the circumstances.
If it happen just once, I would still be pissed, but it's been happening EVERY.SINGLE.TIME. So it makes me absolutly livid. It's just not acceptable.
So to prevent it I've just been deleting them as soon as I get them, or reading comics on other sites so that my wall does not get filled with the thanks posts.
