I've no problem with people talking rubbish. I do it myself a lot. However, posting several replies to a post in a row destroys any conversation that takes place, particularly since the multiple quote feature is currently disabled.
Since everyone has lost a lot of posts then people will be inclined to post more, which is good in a way but it will lead to threads like this. When things like that happen in normal threads, which it undoubtedly will, it'll be unpleasant for everyone.
Perhaps a block on posting consecutive messages could be enabled? Members could use the edit function if they feel they've left out a point in their original post without the need to add another. The minimum number of characters per post is great, btw. I like that a lot but it would be better if more difficult to circumvent
