It feels like they're trying to be a sort of "wikipedia" of every programming problem and solution.
That is exactly what stackoverflow is supposed to be. It's not there to answer your question about "why is my IF statement not working", it's there to be a resource for all developers. How is a question about your specific problem gonna helps anyone ? If you haven't, take the time to read the "how to ask" section, it describes what kind of questions are acceptable and what kind are not.
There is, obviously, some proper questions that should not have been deleted, but most of them are not suited for the site, as they don't bring anything to the rest of the community.
I'm not sure what you mean by "low effort"? OSRS is an incredibly good game and keeps getting new content all the time. I'm happy to pay 15$ a month since we get a free update every wednesday. Sometimes it's just some hotfix , other times it's a whole new boss or continent. We had an new part of the map just last week.
Yes there is bot, but I never felt like it impacted my gameplay other than lowering the price of some items. The team is also doing a lot to ban them, it's getting much better.
The community is booming. If you look around on YouTube, there's a lot of content creators doing awesome thing on OSRS: custom game mode, weird twist on existing challenges, documentary, etc.
Honestly, I think we are currently in the golden age of Old school RuneScape, and if you feel like the game is bad or low effort, it might not be for you, which is fine, but the game itself is not the issue.
I hope you find some other game to give you what you had with RuneScape back in the days !
