Odd thing with upvoting and downvoting

So obviously this bug is occurring on the boards and not in the game. Of late I have been having issues upvoting posts (or downvoting them). On one occasion it told be I had to be at least level seven. I am obviously higher than level seven. On another occasion it flashed an exhaust icon randomly. But on most occasions it just flat out ignores me. I wouldn't have brought this up but I saw a comment on the weekly roundup were someone mentioned something similar so I thought it might not be an isolated case.
