TL;DR: My voting pattern isn't about you. I don't know you, I don't care about you. My voting pattern is based on what I think is best for the site, and the questions that are asked on it.
I'm probably one of the people you think is abusing you. I'm definitely one of the people who tends to vote down your questions, rather than voting up. But not because it's "Tim", but because of the questions.
I only joined the site a couple of years ago (I was between jobs, and bored) so pretty much answered all the questions. It was part of my morning routine; get up, have breakfast, answer a dozen Unix questions, then watch Person of Interest (I'd just found the show and was catching up on Netflix).
Sometimes questions weren't understandable, so I would comment asking for more details, or sometimes the question was almost right, so I would answer them trying to take into account all variations of the meaning that I could think of.
Sometimes the question showed some basic misunderstanding of the concept, and so the question wasn't meaningful. And I'd take that as an opportunity to explain the basics, and how stuff worked. I'd spend hours on it, with examples, proof of concepts, edge cases... I wanted to create the best answers I could, and I had the spare time ;-)
And sometimes, not often, the person writing the question would attack me, and then I'd find the question got edited and rewritten to mean something totally different.
Roll forward to the present. With two years experience under my belt, I notice some common patterns...
An obvious one is people asking for help on their homework. Oh don't I feel dumb for answering those questions, 2 years earlier. Now I just ignore them, or maybe downvote. I can't even be bothered to VTC "duplicate" anymore. (My girlfriend is a director at an Ivy League college, and she tells me the professors there include using StackExchange to answer schoolwork as cheating. Heheheh).
Another obvious one is people asking for answers that can be solved with 3 minutes of google. This is clearly not showing any research effort; they get a downvote.
Then there's those where the question is unclear. If it's only marginal, and I think it can be rescued then I'll comment on it, and maybe downvote. If I think the question is gonna need rewriting from scratch then I'll VTC "unclear".
And finally there's the "WTF does this even mean? When I apple, banana? Huh??" These get a downvote and a VTC.
So I took a look at the questions you've opened and looked at how I responded to them... and, yes, a lot of them have been downvoted or VTC'd.
But not because it was "Tim" asking the question, but because I felt they were bad questions.
Nothing so far has been "Tim" related.
Now a personal comment on you.
When I do leave a comment on your question or try to answer your question, you attack. You play the victim in these threads, but you are the biggest bully I see. You play passive-aggressive (eg your profile comment), you attack people who try to help you, you rewrite questions with nasty remarks in them.
Despite that, I do still try to answer your questions when they are something that doesn't take a 50 page essay (VTC "too broad"). Sometimes you accept them, sometimes you leave comments which make me think you didn't try to understand (e.g. google the concepts mentioned) and just jumped to a "what does XYZ mean?" comment.
I still answer the questions because a goal of SE is to build a library of answers. Whether you appreciate the work doesn't matter. I'm just trying to make it the best library I can, within my limited means.
I'm guessing English isn't your first language, and this may not be helping you (picking the wrong words, so people misunderstand you; phrasing things the wrong way, so people take umbrage). You might want to step away from the keyboard and breathe for 5 minutes before responding; don't say the first thing that comes into your head. Go to the kitchen, get a glass of water, calm down, assume the other person is trying to do the right thing, engage in a construct manner.
In summary, see the TL;DR at the front!
