I'm going to start by saying something that many of you have probably said to your children at some point in your lives: treat others how you would like to be treated.
In January of 2011, I jumped into a community of people who are extremely caring about other mamas, who share about their life experiences with diapers, and HELP each other out.
It doesn't matter if these mamas run online shops out of their homes, have brick-and-mortar stores, have blogs that they run, are WAHMs who make diapers and other crafts, or whatever... every one of these wonderful moms (and some dads) are extraordinarily hard-working people that contribute greatly to the community.
They work diligently to produce items for you and your children, and if they aren't actually making the product, they are reviewing it and setting up awesome giveaways for YOU. Many of them work late into the night (seriously, it's 2:17AM here and a few of them just got off Facebook, and they are east-coast time so it's 3:17AM there) to bring you these.
As you may have noticed, several of them have required components of their giveaways where you need to go check out a website or follow/fan a page. There is a reason for this, and quite frankly, un-fanning after a giveaway ends is unacceptable.
Again, un-fanning or un-following a page after a giveaway is over is NOT a nice way to behave. I see this happening more and more where giveaways occur, then end, then the next thing you know people and pages have dropped tons of fans.
This is hurtful, and yes, it's a little disrespectful. Even if you didn't win, at least be appreciative of the hard work that went into bringing you a giveaway to give you an opportunity to win. The message that is sent when you un-fan or un-follow a page is that you don't care at all about the behind-the-scenes work that went into this. Imagine for a second that you spent hours preparing giveaway items for review, then you come back and see that you dropped 50+ followers and fans? It's unacceptable behavior, plain and simple.
Somebody told me that at some point Facebook will put limits on how many pages you can follow. However, this isn't until you reach well into the four-digit mark. What I'm saying is, don't un-fan. There's no reason for it.
Happy being grateful for giveaways and NOT un-fanning/un-following/un-anything, and treating others with respect.
