I think there are some people who use it way too much and then it ends up flooding your feed. Then those people who do it excessively end up getting muted or something like that. Maybe not all the time, but I have seen it happen. I have also had it happen to me.
I have said it multiple times already, but no one noticed.
There should be a way to mute/ignore just reblogs from a specific user without muting or unfollowing them.
I have seen people unfollow others just because someone was reblogging a lot of accounts that the other guy wasn't interested in. I know there is a filter to exclude reblogs but that filter just excludes every reblog rather than just those that we want to exclude.
Yeah, that would be cool.
