So far you've asked a question 9 times and answered a question 7 times.
Only 2 out of the 9 questions you have asked (excluding this one) has been downvoted (this onethis one and this onethis one); personally I wouldn't have downvoted either of the two.
Only 1 out of the 9 questions you have asked (excluding this one) has been closed (this onethis one); personally I would have voted to close it as well.
Only 2 out of the 7 answers you have posted have been downvoted (this onethis one) and this onethis one); personally I wouldn't have downvoted the first one, but I would have downvoted the second one.
But checking the questions and the answers that have been downvoted, I saw thisthis comment (which I flagged):
I can't comment I don't have enough reputation because of dirt bags like you who mark down other peoples answers without offering their own answer
And now your question here on meta. (migrated)
Now it's not the first time that someone gets downvoted (for a right or for a wrong reason; here's just the latest post on Meta), but in any case you still can't go around calling names, even if you're in right.
I partially agree that not all of the downvotes you received were deserved (but that's just my measuring, not each one's measuring).
I've checked all of your answers, and I wouldn't say they are bad, but they're indeed concise; I agree that sometimes a concise answer is enough, however, speaking of the most recent non-downvoted answer you gavethe most recent non-downvoted answer you gave, for example, you could have explained how to download and install WINE, Steam and VirtualBox (it would have been a matter of writing two apt-get
commands) and I would have upvoted it, nonetheless also explaining (even concisely this time) how to install Windows on VirtualBox would have make up a great answer.
Don't call names (ever), try to answer more thoroughly and you'll see that really good answers get lots of upvotes.
