Well... I dunno how it's normally done in chess, but in pretty much all sports the #1 guy gets paired with the last guy, the #2 guy gets paired with the second to last guy, and so on. Judging from what you said that certainly didn't happen, but I'm pretty sure that you're not supposed to be paired with the 4/4 guy, because first seeds don't get paired with second seeds.
Attention:Chess.com Your tournament pairing system is a joke!

How many players were in the tournament? If there weren't that many, the rule that forbids players from playing each other more than once in a tournament may have been the cause. If there was no way to pair you and the top seed without having two other players play each other for a second time, then the USCF rulebook says (27A1) that avoiding the repeat pairing is the higher priority.
Maybe it was compensating for colors as well
Internet chess is serious business.
Based on my experience, how pairings in chess.com tournaments work is:
Suppose their are 8 players, seeded 1 - 8. Then the pairings are:
1-5
2-6
3-7
4-8
Personally I've also found this a bit srtrange. I think what happened in the OP's case is that the 1050 was seed number 5 in the example above, and the 1450 was seed number 6.

Those are correct first round pairings for Swiss events. However, in subsequent rounds the pairings do not follow standard Swiss rules. More than once, I've played the same player twice, or played someone with more than 1.5 points more or less than me. Both are highly irregular.

Those are elimination tournaments. Swiss events are non-elimination. In FIDE knockouts, the system that you describe is used.
Elimination: top plays bottom.
Non-elimination: top plays top of bottom half.
No, here's how I know the pairing system as. Put players in ascending order according to rating. Unrated players are put in order alphabetically at the bottom. Divide all players after putting into order into half. Top player of top half plays top player of bottom half, and so on. But I think yes, after first round not traditional Swiss pairing system.

It is impossible to have played the same player twice. If there is a situation where it is impossible to pair without having two players play again, the tournament will automatically end.
It has happened to me twice. It is possible that they have corrected the defect since. It was a while ago, and I complained at least once.

So in other words, under Swiss rules, it's best to be seeded just above the 50th percentile?

With common sense, they never played each other. One guy had 4 wins, the other had 3 wins 1 draw. for them to have possibly played eachother, either they both would've needed to draw, or one were to have lost. So no. They didn't play.

Unrateds are at the bottom. If you want to be assured a win in the first round, those aren't your best odds.
No matter where you are seeded, upsets can and do happen. I lost in round one on Saturday. My opponent won the prize for biggest upset. I was seeded fifth in a pool of 29 players. In the last round, I played number one (who lost to number four in the third round) and lost again. It was my worst tournament in several years.

Are you seriously pissing and moaning about a 10 minute rapid online chess tournament? Last I checked, chess.com wasn't awarding GM norms on winning these "tournaments", lol. Not to mention half the field for all chess.com online tournaments withdraw after the first round. WHO CARES, the entitlement attitude on this site is ridiculous

The site claims to use Swiss pairing rules. They do not. The site errs in implementation of these rules. The site can easily repair these errors.
That's certainly an issue whether its affects the price of tea on the black market or means nothing at all outside the world of a few cybernerds.
Are the pairings done automatically by the software or by a human? If by a human, I can understand errors being made because humans are imperfect and can often make mistake if they are in a hurry, under pressure, etc. If the pairing is implemented automatically by software, then someone should find the bug and fix it.
It must be done by software.

Of course its software.
Who does the pairings for your tournaments,a monkey? Today I was playing in one of your G/10 events. Going into the last round I was in sole 2nd place with 3.5/4. The first place player had 4/4,and if you go by USCF pairing rules,the only legal pairing was for me to play the 4. Instead,he gets spoon-fed a 1050 player with 2 points(???),while I get a player rated 1450 with 2 points. That is total BS and downright illegal,in my book. I used to be a USCF TD,so I know how to do Swiss pairings. Until whoever runs your tournaments learns how to do proper and legal pairings,I am not playing on your site again.
