My two cents (most likely unwelcome)
After quickly looking at your posts I'd say you tend to be combative and insulting to other view points, hence the downvotes.
There is even a chance that your comments are disliked and it may not be a single person doing a round robin.
Either way it's an open forum. You are free to be belittling of others opinions and they, whom ever "they" are, are free to downvote you.
An example of one of your feather ruffling comments:
>> The RTM is out now
>is it? I haven't seen any information to that effect
Straight question, downvote... Oh, I get it! A person with severe learning difficulties has noticed I said things about Android which were not complimentary and also true and so s/he is downvoting everything I say, even straightforward questions which actually draw doubt on the statement of somebody advocating WP!
You poor thing. I hope your carer gives you a lovely cuddle later.
