No matter if swastikas should be or should not be banned, please stop talking about it as
1) it's not allowed / encouraged to complain about forum rules here
2) even if you complain that will not have any effect
3) it's extremely annoying to have the same discussion year after year
4) when you signed up, you agreed with the forum rules
5) topic may get banned from off-topic swastika discussion
It's good to say for a person who has posted swastika, that there's a swastika in his post. This because
1) he may have posted swastika accidentally, for example not noticing the swastika in a picture or so
2) he may not know that they are not allowed
3) he could get banned from posting swastika
If he's told about the swastika, he can delete it.
