Would you like to have more or less contact with them?
Both. More contact in that we could question them or raise an issue without fear of a ban. Less in general.
If you avoid a couple of things, I can truthfully say you won't get banned for asking a question or raising an issue.
First thing: Don't send shock porm in your pm.
Second thing: Don't start your pm off with something like.. "Are you out of your [censored] mind you [censored] faced [censored] idiot? Are you naturally [censored] or did you study to be that stupid?" Even that would usually be a warning and suspension for flaming rather than an outright ban. [Unless the person was on their last warning, of course.]
Generally questioning our parentage, species, gender preference and giving specific directions on where to go and what we should do once we get there should usually be avoided as well. Most of that would end up being a warning and posting ability suspension, though, except in the last warning case thing. [We log complaints and issues in the Admin/mod forum so the admins can see what is going on if the poster wants to take their issue to Gstaff or Nick. It can be rather interesting to see the creative language people can come up with at times.]
Oh, saying you pirated any games would also be on the "not a good idea" list. There are very few insta-ban offenses in the rules, but the ones that are there are enforced.
