Good evening, @sherlockholmes. I potentially have a case for you:
This evening, I received 30 votes in a very short period of time (2 hours). Of course, I would LOVE to think it is my content that drew in so many upvotes until I saw defreca's comment below. Because she has a number designation of "4" next to her name, I became curious as to why she is at that level.
I didn't spend too much time (I am a little tired and will investigate more tomorrow) on the content of her comments, it just seemed that she had commented A LOT in a short period of time.
So then I began to become suspicious of all my sudden upvotes, so I started to see who had voted for me. The 4 names that I clicked onto at random had been activated this month with no comments, posts, or followers. Curious.
Now I love to have people read my posts, not just vote them up......
Anyway, I am sure you are busy but it seems strange to me that I am suddenly getting a bunch of upvotes from people who have no history whatsoever on Steemit. Weird.
I will check more thoroughly tomorrow. If you have any suggestions on what I should do or where to report this strangeness (or if I should even do anything).....well, I appreciate your help.
I always enjoy your posts, @sherlockholmes! I am one of your biggest fans!!
