Student issues are always going to be the same. Some new concerns may come up, but basically, the student woes remain the same year round. The pattern of scams run by the essay companies are also becoming more intricate so the students need to be kept abreast of those new information. However, old information will always have some sort of usefulness. More along the lines of educating the students about how the scams evolved or, for some students, the old postings that are revived become part of their learning experience. Let's think of the situation along the lines of history books.
History books never lose their relevance. The lessons taught and learned educate the students and, in some instances, become useful to them when dealing with certain situations or learning demands. The same goes for the threads here at ES. There is no expiry date on the posts. The posts need to be kept active so that students can always find a reference to whatever it is they are looking for or, simply to educate them before they get scammed.
There is nothing wrong with reviving old posts. The students are going to benefit from it, regardless of the opinions of the old guards at this forum. It is their "expiry date" mindset that will eventually make them irrelevant at this forum.
