Twice at the most these days :)
what is your opinion of the Hivewatchers soundbite that they consider more than a post a day as spam?
I don't think they say that, but it also comes down to perceived value. Very few people can produce something of value daily, let alone multiple times a day. Those that do, are likely plagiarizing or using an AI.
I know that over the years, my content has been investigated by people multiple times, but since everything I write is mine and it doesn't appear anywhere else online at all, it is above reproach.
There is also the question of engagement to be considered, where people are posting multiple times, but not getting comments on any, or commenting on other people. They aren't building a followership or looking to add value, they are just posting for hope of reward.
The rule itself (first I have heard of it) is not a bad rule of thumb. For a decent content creator, they should be able to produce something of quality daily and have the space to engage and build an audience. The farmers with automated posts, stolen content and using AI as if it is their own work, screw them :)
