I'm pretty sure I've seen some examples of this but I can't find them now. Besides the better-known pinhole photography, there is also pinspeck photography, and some random object standing in front of the wall could perform the function of the pinspeck.

Then how can you see and reply to my post?

[kaffeemitsahne]

Because I vouched for it first (requires some amount of karma I think).

Is this a normal thing for new accounts?

I really can't think of what I did to deserve a shadow ban.

From what I gather, there are some anti-abuse filters that can sometimes affect otherwise good accounts. When this happens, the best thing to do is vouch for the comments you think are good and contact the mods using the Contact link in the footer.
