I posted a concern somewhere at sometime about amounts being withdrawn from my wallet.  I was told that it was a charge for announcing my host on the network.  I've been hosting for a couple months, and right now, at this moment, I have 10 peers, 18 contracts.  BUT, Sia is using my storage, Sia has made a noticeable impact on my Internet speed, I have not earned a single sia, AND I have a bunch of withdrawals that have nothing to do with announcements:

-149.4504 SC     e41b1f0a4978b9d307df033f5fba3c6b560b48c5347bcd5911b8249993728f0e    Confirmed
-108.3725 SC     f910518e52f15fd303289317dbd870d10faaf3de8d72f3682ad301442ae6dec0    Confirmed

So, after months of having my resources used, putting up with spikes in Internet usage that slow my network, not earning anything, and have sia withdrawn from my account - I am transferring my balance to Poloniex, shutting down the host/wallet, and liquidating the remaining sia I have.
