I couldn't send a PM because computer said no and told me: "You have exceeded the limit of 5 personal messages per hour."yes - its to make it harder for spammers who post messages to users. If its a problem i can increase it
Is this something new?
I wasn't aware that was a thing. I have never received a spam message.
Most of the time that limit won't be a problem, but it can be when you are e.g. conversing with two or more users.
Then the limit of five PMs is very restricting, and also the waiting time of an hour is very long.
Perhaps change it to something like 8 posts in 30 minutes?
