Your favorite writers have stopped updating, not returned from hiatus, or simply deactivated altogether, because they get no support.
If you're one of the people who goes to X writer's inbox and says "I know I don't reblog from you-" lemme just stop you right there.
We have lives. We have duties, things to do, responsibilities, because a big chunk of us are adults. It's okay that you have other things, that you're not always available, that you might be going through something and can't always read or reblog everything. Writers get that.
But no writer wants to see you tell them "Hey, I know I don't reblog from you!"
They know. They're in a slump for a reason. The reason isn't you not reblogging or supporting them, the reason is hardly anyone doing it.
And if you go to them and wave the "hey!! I don't reblog from you even though it's all you ask in return for your free work!" card, chances are, the writer will be upset. They can't very well point out how tactless you're being, because then they might just be cancelled or called out for being rude to you when you are deliberately being tone-deaf to their situation as well.
Like you, writers have lives outside. Writers have jobs, or are searching for them; they have worries, duties, things going on, worries, etc.
The difference is they sit for hours upon hours to write, while it would only take you between a second and a minute to reblog.
Reblogging is absolutely not difficult. Fast reblogging is incredibly quick and practical, but "slow" reblogging isn't slow either. You don't even have to add a comment to the reblog, an empty reblog is just as appreciated.
Supporting your writers is literally not difficult, and if you as a reader and as a consumer aren't going to do it, then it's totally fine if you choose not to. Your life, your blog, your choice.
But don't go at a writer to remind them "Hey I know I'm among the people who doesn't support you but I still like what you write" and expect them to be overwhelmed with joy without feeling the slightest tinge of resentment.
If you're in the position to support a writer, do it. It's not hard.
