Why not ? A channel opening to you does not require anything from your side (apart few bytes of RAM but....), people usually strive to have big inbound channels.
99% of the time it probably would not matter. I was doing an test of some stuff during the week [yeah I know use testnet for testing] and 3 places had opened MASSIVE channels to me. I thought / figured at the time it was a mistake. In the time I have been playing around with LN in TOTAL I have not sent & received in total as much as any one of those channels. And then an hour or 2 later they closed them.
I mentioned it to someone Friday who said, "yeah I had the same thing happen a week or 2 ago" he also mentioned that it did not appear on 1ml or other LN explorers. I did not check on mine. Just big open followed a bit later by a big close. So somebody is playing around with something. Which is fine but, I just did not expect it and was wondering if there was a way to prevent it.
That is probably what I am look for. Thanks.
