When browsing in All or similar, there’s a non-zero chance of coming across things that can be offensive, explicit, or disgusting. You shouldn’t encounter anything pornographic or where people die or get horribly injured, but that is my only expectation.
I browse in thumbnail view for that reason. It’s enough to see if I want to see a full image, if it’s not something I want to see, I didn’t get hit full blast by it, and if it’s something I don’t want people around to see at that moment, it’s much harder for them to see it and faster to scroll past.
When you select a sort that pulls from every community, it’s you asking to see everything. Death, injury, and private parts are about the only things the bulk of society can agree are at least somewhat offensive, so those are the only things you should expect to see blocked by a NSFW filter. Lewd, gross, and offensive are still free to pass, for better or worse. That’s the Internet culture has existed for most of its existence and feels pretty universal in my experience.
Scripting is the closest thing to magic I’ve seen in real life. Wave your hand over the script and poof, a job is done.
I automated so much at my last job I usually never “worked” more than a half hour a day. I am not a programmer, but I slowly learned enough Excel functions and VBA, then simple batch files and some AutoHotkey. Since it was only stuff for my job I needed to learn to program for, it took much less time than learning to program for any situation. Also much of your work is going to be relatively the same as many others’ work, so there is a lot of code out there you can lift from and tweak until you learn to build it from scratch.
