The act or acts of posting your supposd intention to delete your ID from an online community, for the purpose of attention seeking or sympathy.
Deletabation is often practiced by saddos when they feel left out of the community, but have nothing of any real value to add to conversations etc.
Regular practicers of deletabation are known as deletabators.
The site became so polluted with deletabation that it was hardly worth visiting any more.
It was yet another example their of deletabation, when for the third time in as many weeks he/she posted their intention to leave, and sat back waiting for the messages of support and pleas not to go.
It never ceases to amaze me how gullible fools fall for his/her blatent deletabation yet again.
