I agree, I send polite contacts and get ignored. I am a grown man, thanks but no thanks, have a good life is cool. Ignoring a contact, when you have a profile on a dating site anmd are inviting contacts is poor form. Sorry ladies, but it is. Courtesy costs nothing.
That said, I have not contacted anyone on this site other than for conversation and all have been very nice.

What ever happened to meeting people the old fashioned way? I met my last girlfriend in a bookstore, and the one before that at a mutual friends party. I used to belong to a couple of dating sites, and like Cptnron59 says, it was pretty difficult to say the least. Take care and good luck

There are a lot of a scammers and they are getting better at it. Perhaps your messages are mistaken for a scammer.

Yes, often times men get nasty when they hear not interested. They refuse to accept that 2 hours is too far away. Or any other reason a woman gives.

I once gave my primary email to someone and he figured out my real first name and was pissed that I used a different name on the site. Sent me many rants about how I was liar and bitch etc.

Another time, a person connected to my employment saw me on there and thought it a good idea to bring it up in front of my co-workers.

Sometimes I log on when I get a notification but most of the time, I just ignore the notification.

Because we're damned if we do, and damned if we don't. Sometimes I feel bad not replying, but then I'm also not up for receiving an abusive email in return.
A bit of advice for you - be open to the fact that maybe this isn't just a problem with the women.

I actually prefer them not to say anything. I guess I tend to message them and forget about them. If they message back saying no I feel rejected. Sometimes they’ll actually tell my why, like they aren’t in curvy women, etc. I guess a few have said the distance is too far but good luck. Of course I’m hard on myself so I assume that they just think I’m ugly. I generally don’t message someone who is more than 90 miles away. I don’t think an hour and a half drive is too far.

there all bullshit and about money.

I read way to many accounts of guys going off on women who say "no thanks." These men seriously seem to think that she owes them something because they find her interesting or attractive or whatever. They harrass, belittle, shame and just generally try to make her feel miserable because she said no. I totally understand why many would not respond at all in order to avoid that.

I'm not saying you are one of those guys, or even that they are in the majority, but how does she know that until it after the fact? It is truly unfortunate because it could be so much better and civil all the way around.
