I noticed that I have accidentally casted a down-vote, and now it is locked for removal.
I noticed this by my reputation gain not being equal to a multiple of 5 and when I looked it up (I thought somebody gave me a down-vote) I found out that this down-vote must have occurred accidentally while browsing on the small touchscreen of my phone.
This happened before and in that case I made some cosmetic edit to the post and removed the vote. This does not really seem like a good option especially when the answer/question is fine.
Is there a better way to remove a locked vote?
