It's generally considered very bad form to denigrate, or even unnecessarily mention too often, one forum on another forum. It's certainly bad form to drag personal disputes from one forum to another. We've had several members that have earned the right to be called "serial pest" because they steadfastly refused to abide by either of these principles. Which is a shame, because many of these serial pests have quite good knowledge of coins and numismatics, and would make excellent members on any coin forum if only they were less... sociopathic.
Not saying that any of the people so far participating in this thread or the thread on that other forum are like or have done anything like this. It's just a general comment on the subject.
For specific comment on the subject mentioned in the OP...

...have sometimes been puzzled why quite good posts have just disappeared.
No problem with that as long as a message is substituted to advise what rule has been breached.
As a general rule, the mods here prefer to edit out minor breaches of the rules, rather than delete an entire post or an entire thread. Occasionally, an off-topic but nevertheless worthwhile comment will be split off into a new topic of its own and moved to a more appropriate part of the forum - it might look like its been deleted, but its really just been moved. However, deletion may be required if a serious rule breach has occurred or the post is of such a nature that it would only encourage other members to respond in kind. Making political comments, for example.
Finally, I should add that the admins and moderators are not rule-fixated cyborgs but normal fallible human beings. We can make mistakes and errors of judgement - such as deleting something that looked at first glance like spam, but was actually a necessary and important part of the discussion. If at any time anyone feels a post of theirs or one they were reading was improperly deleted, you can e-mail one of the admins or moderators and calmly and politely make your point. But I've found one thing to be universal, both on the Internet and in real life: an expletive-filled tirade will rarely get you the result you were seeking. I'm always amazed at how many people think such a tactic will work with the admins here.
