I upgraded my first post with some links and I want to use the opportunity to respond to some concerns about the sticking of the posters.
First I will start by saying that:
- poster advertising is 100% legitimate and does not violate any prohibitions.
- there are places where posting is forbidden, and I never stick to them.
- in many places on the apartment buildings there are bulletin boards and I stick on them
- there are places where people have written that they do not want ad sticking. I never stick to such places
- I use tape for sticking. Where there is no message board I use the windows of the residential entrances. That way posters are easy to remove and leave no lasting traces.
- but sometimes there are residents, and when I ask them if I can stick, some of them tell me to use the wall at the entrance (others want the window)
Everything is extremely polite and so far I have not even had one complaint (over 1 year already).
