I attempted to register for several accounts but a message came on saying my server was blocked due to spamming.
My IP number serves many people because it is in a tourist hotel from which many people come and go constantly
In other cases websites I have been able to reach before are showing 404 Gateway blocks.
I think this may be a new form of censorship in which the IP is put on a blacklist preventing communication by internet users in that location
Such a blacklist would have be triggered either
1. from pressure on the blacklisting company from an external party to get a false listing,
2. or someone would have to have entered the building and used the internet connection for spamming to get the IP put on the blacklist.
Can any suggest a way such blacklisting can be lifted? Can the IP number be changed?
Does the DNS number have anything to do with it?
I am not the manager of the building and have no control over the wifi router or the server.
