This is tragic, and my heart goes out to the families and friends of the recent suicide victims.
I would like to offer an additional perspective - teasing/bullying has been around since bigger neanderthals picked on smaller ones, and while we have become more intelligent, our teasing has only become more brutal and organized - and it is unfortunately a part of growing up in the world as we know it.
I wouldn't spend a lot of time hoping or thinking that this is something that will change. It's like hoping that thieves will stop stealing or the concept of war would evaporate.
Our focus needs to be on boosting the personal strength of the individual - building characters that can cope with adversity at school, or in the workplace, etc. A strong, well-developed sense of self, even if lacking complete confidence - will not turn to suicide as a response to torment.
Rise up people - BE STRONG! Be who you are and move past the idiots who don't like it. It is your right to have this life as much (or more, some might say) as the morons who are teasing you - your one obligation is to keep moving forward, and under no circumstances, check out of the journey.
Princeton.edu says a victim is "an unfortunate person who suffers from some adverse circumstance" - but suicide "victims" self-impose their victimhood.
Suicide is SELFISH. Suicides leave children without parents and parents without children, wives without husbands, etc.
Finally, if it seems as if there is no other option, it may be that you are seeing it from the wrong angle - and you need to reach out for help (friends, family, professional).
If that help doesn't arrive, then guess what? - you march on anyway and figure out a way to grow from it - because the alternative is unacceptable.
This is your life to live. Live it.
