If that were true than wouldn't the same rules apply to gamertags? I haven't met very many people who made alternate gamertags after significant change in their personality or dealings with past people. That makes account purges on websites a unique facet. Out of all the purged accounts I've ever met they all shared similar psychological processes. Shame, guilt, embarrassment, or significant emotional disruption due to being on the website. They forced themselves off the website for those reasons because it was a dual aspect of both being an addictive coping mechanism while being disruptive to their mental well being. There's always outliers to any statistic, but the common trend that I've seen in people who demonstrated higher emotional stability or awareness was to simply leave the website when they felt like it. They could vanish for years and come back a different person entirely without a need to purge anything.
