Do you actually need a good reputation to be successful in a platform that caters to mostly brain dead on the toilet chatter?
If you care about your online presence and the branding "value" it has, then work to separate the brand from the platform as much as possible.
If you care about your social connections, find some way to separate them from the platform too: follow them on another platform, learn their general identity so you can find them elsewhere, and maybe we can all try to value having our own personal homes on the web separate from any real platform again.
