Yeah, a bunch of extra accounts is understandable, but Im taking thousands here. You can simply power them up and then down. Considering back then each a/c gave you 10 SP on signups unlike 0.5 now, powering them up to power them down means a LOT of SP multiplied by the number of a/cs you own! ;)
Then you can simply delegate SP to the same a/cs and have them follow you or author of your choice in a trail! :D
