The spike after the vilely negative ones may not be from your responding in kind, but from sympathy after you get a vilely negative review, which will be eroded away after you respond in kind.
I freely admit I gauge visible author behaviour using a milli-HarlanEllison scale of "you must be at least
this talented to get away with certain stuff" and while I may occasionally be willing to read works by authors behaving badly, I am considerably less willing to pay actual money out of my own pocket to do so, and considerably less likely to recommend them as a worthwhile read to others (unless the talent really has sufficient milli-HarlanEllisons to justify).
In fact, I consider creator w*nk to be a prime source of free entertainment which is probably going to provide me with more lulz than the actual story/book/whatever. But I digress.
Anyway, if you are determined to respond, should you ever find any of your responses being essentially a paraphrase from the
Bad Review Bingo Card, then you may want to step back and rethink your response before posting.
Or not, and provide some bonus free entertainment.
