I upvoted your first comment because it was insightful, interesting, and added to the conversation. I downvoted this one because complaining about downvotes is largely considered to be in bad taste and doesn’t really help anything. I did both of these things before I realized you were the same person.
Yes, for sure I deserve downvotes for the above. Those types of comments should be downvoted. However, I needed to post it to point out that I got the -10 well before the comment above. I never experienced that before and thought it interesting enough to share. Karma doesn't mean anything to me personally. But burst behavior like that is unusual.
