Has Yahoo Answers been hacked?

I think the recently announced 1 billion accounts, Yahoo hack, has impacted Answers, because, starting just this last Saturday, I have received numerous Best Answer notices, most from Yahoo Canada, and some as old as a year, or several months old, and a number just recently.

With all the trolls, who would notice.

I report Clear Violations of the Terms of Use. and they continue, as they have for a year or more.

Some do seem to disappear, but others more established continue on and on.

You would think that a count of 2000 posts with a score of only 10 or less points, would be indicative of a worthless Troll, but no they continue posting their "lol", "ok", "I dunno", "k", spamming "no", "yes", (as their only answer to everything regardless), "1", "2", "L" (whatever that means).

A help in disposing of the them might be to make the Report Flag (red) more visible, It is hidden because Yahoo does not want it used. The Down Thumb is Useless for getting rid of the trolls.

anyone on Yahoo can give answer to your old questions as long as yahoo exists, has nothing to do with your password or email account, it is your question you posted in the past that is available forever now

I think they're just people trying to get more points by copying answers or other irrelevant sentences and posting it on as many answers that they can, including on old answers.
