If you really want to get informed about the protests in January and the death toll start looking at Amnesty’s report and you’ll see the 30000 is not dubious. Cherry picking who reported on a piece of news doesn’t invalidate the content of it.

I could not find the 30000 figure in the link, while it does mention "thousands", what is contested here is the fact that 30000 is an order of magnitude larger number.
The fact that your account is only used to comment about Iran is also weird.
