emilie people were putting last SI yesterday in their signatures. Or a huge list of things such as last cut, last burn, last OD, last suicide attempt, last purge, ect (yes people did do that.)
What you suggested was in the original poll when this long debate happened and it was thought to be too "big brotherish" for the mods to make an amount of time that was acceptable. Also that couldn't eliminate the log list of lasts.
The bracelets never became vogue anyway and I can only think of one person who has used this in the past two months.
I hope this helps.
