Sorry everyone, but prepare for a massively long rant...
Seriously, spam accusations usually come from newbs who are trying to cover up the fact that they lost. They need to find an excuse.
So whenever someone calls me a "spammer", I simply reply with "Nice try, no Johns". If someone says "all you do is spam", I like to reply with "all you do is suck massively".
I know I'm coming off pessimistic, but I think that a lot of newbs are prone to calling any Zelda player (and to an extent Sheik) a spammer regardless of how what you do.
I've had plenty of matches where I used all of Zelda's moves, tilts, etc. Barely used Din's. Probably about 3-5 times over 3 minutes. But when I did use Din's, it was as an edge-guard and they died. As soon as the match ended, I got called a "spammer". The proper response is "no johns".
I dunno, the players who complain about "spamming" basically use that as an excuse to cover up their (in)ability to play well.
If your opponent is spamming the same thing over and over, and you're losing... it's because you keep falling for the tactic... Why should another player purposely give up an effective strategy? That doesn't make sense.
One player called me a spammer because he continued to roll into me over and over, trying to grab out of his roll. So I down smashed him over and over, every time he did it. He then proceeded to call me a "spammer". Maybe he was right, I should have given him a turn to hit me instead of punishing the same mistake over and over.
Furthermore, most of the people complaining are complete hypocrites. I played in a tourney where all my opponent did was camp with Snake, throwing grenades and such the entire time. It was pretty annoying, but i didn't say anything because it's a legit tactic. The next round I changed to ROB for the fun of it, then obliterated him because he kept trying to camp me and ROB out-projectiles him fairly easily...
When the match ends, he starts johning and saying "all I do his camp projectiles, gyro, laser, gyro, win. Do spammers even feel good about spamming?"
There you have it. I'm a dirty "spammer" because I counterpicked a character who he couldnt' outcamp against... even though he spent the whole first round projectile spamming me so he could abuse Snake's tilts when I got to high percent... I'm the bad player because I beat him at his own game.
Hypocrite "anti-spammers".
Then there are my other favorites. People who play Marth, Meta, etc. Characters with exceptional approaches, high priority, and good combo/killing power. They get mad because you use projectiles to force them to approach. They condemn you as a "newb spammer" because your not the one making the approaches. Because Zelda, with her poor approaches and weak air priority (unsweetspoted) really needs to be fair and approach these types of characters.
Never feel bad about these types of players. If someone is playing Marth, Meta, etc... and they can't approach past a fireball, well then they need practice. Because in exchange for not having any way of forcing their opponent to approach, they are blessed with massively high priority and awesome aerial games. Yeah, you should feel real bad about shooting projectiles at a character who can outprioritize you and and whose sword can reach through the hitboxes of your strongest moves.
These players are good enough to try and belittle your win, but not good enough to do anything about it.
I'll apologize once again for my long rant, but seriously, no johns. These people try and make you feel bad for winning, even if your not spamming. So next time the word spam comes out of their mouth, "no johns". Let them stamp their feet and throw a hissy fit... they lost. No johns.
I'm all for hilarious johns that are said in good fun, when both people know it's a joke. Silly excuses that aren't really excuses as much as an opportunity to be funny. But trying to tear down your opponent's victory because you suck is low.
I know everyone does it from time to time (or is at least thinking it, even if they don't say it)... but honestly, if your johning after every match or blaming your losses on "spammers"... maybe you just need to blame yourself.
Besides, it's not like there's a giant trigger called "R" located on the shoulder of the GC controller... some would call it the counter to projectiles. You press it, and then it magically dodges/blocks attacks.
