It should be fixed. If you browse each of the 5 tags you used using the "new" filter (sorts by time), you should see your post in each of the 5 tags, at whatever time you posted them at.
The @asshole flagging thing is unrelated, and just someone's stupid bot that randomly flags people for no reason.
I got it and I don't worry about that stupid bot. It was strange that he downvoted me only after I took off one tag. Thank you very much for the feedback.Cheers!
