What warnings fo آپ typically avoid? Which ones do آپ not mind? Are there any that آپ look for because آپ enjoy those particular stories?

None.

But once I've clicked on a story, it doesn't take me long to check if I'll read it یا no. If grammar, spelling, reading-friendliness are poor, I'll just back off. Shame there is no warning about that !

I check summaries first. I'm a bit of a grammar/spelling fanatic, so if the summary seems off to me, I probably won't read it. Oh, and once I start reading and people starting using 'internet-speak' like "plz" and "thnx" and "sed" in the story, I'll immediately click out. Anything else written online I'm okay with that, but I can't stand reading it in an actual story. Unless someone's using it to دکھائیں a text-message یا something.
