I read the first post in this thread and then started to go deeper, then stopped(hey, I'm old, I could be dead any second).
I'm new here so my opinion doesn't carry much weight, and that's okay. But, I come from a place I called home for many years, where bombing was common, fun and heart felt.
I've done both, bombing(when I could)and receiving. I don't think anyone of the guys that hit me did it to get "attention" they did it because it was fun, or, because some poor slob was going through a rough patch and someone wanted to make them smile, if only for a little bit.
I did it...because, I could, because some poor slob was going through a rough patch, and I hope, I made his/her day just a little better for it.
Bomb for the right reason? What "right" reason do you need? The right reason is...up to you!
Never feel you have to, to "fit in". Never feel like you "have" to make a big deal of it, if and when it happens, and never, ever, feel you have to get "pay back".
To end, bomb or don't, but, never feel bad about either...and that's all I have to say about that
