Anyway, this is the only topic we came up with that nobody disagreed with... so, without further ado... Here's an amount of reasons as to why we'll stop following a book blog.
Blogs that do nothing but post buy links on their facebook post and/or spotlight blog tours on their blog. This is actually called spam, and it is why facebook and blogger have changed a lot of their rules lately.
Blogs that get their following by bashing books. I get it, saying negative things gains attention. Being able to say a book sucks is nice. But there are ways to rate a book negatively that isn't someone being mean just to be mean. And there's no way every book you ever read is that bad.
Blogs that will only post about books of the same genre. It isn't that we don't understand this, because we do. It's what you enjoy, and that's great. Thing is, we're all very diverse with what we read. If we read some super shmexy romance, the next book we have to read is graphic and full of zombies. Seeing too much of the same genre is a turn off for us.
Blogs that never interact with their fans, or post things with engaging content. I don't know about you, but I feel if someone asks a question and then just leaves it hanging open that they really didn't care about my opinion in the first place. One of my least favorite things is to feel like nothing more than a number.
Blogs that are quick to bash, or refuse to read specific types of authors. Look, we get it. You like what you like. There's nothing wrong with that. But when people start saying certain types of authors are not good enough for them, that's stereotyping. Unless there is a group of authors called, "Horrible Book Writers". Because I'd probably avoid those as well.
Blogs that don't give less than 4 stars on their reviews, especially if I read a few of their suggestions and completely disagreed with their ratings. This is similar to the blogs who only do negative reviews. I get those people who won't post their negative reviews publicly as well. What I don't get is the blogs who will rate every book they read 4 or 5 stars, even if they're not good, because they don't want to upset the author. It would be so much better if you just didn't review the book at all instead of lying about it.
Blogs that only do giveaways. This is similar to the buy link one. That's good every now and again, but too much of a good thing is spam.
Blogs that jump on the bandwagon of bashing others accused of something (usually piracy) without checking the facts to make sure it wasn't a lie.
Blogs who ask for sympathy over whatever subject just to gain likes and boost interaction. We all struggle. Sometimes it's good to rant/vent and get it off one's chest. But if a blog's entire interaction revolves around such things, it is no more than a cry for attention.
Blogs who are full of drama. The types that are run by people who like to start shit. These are the types that start the rumors, but have a big enough following that people will listen and side with them without needing proof of the situation.
