I said this the other day regarding another discussion here on Meta, but I believe it can either be relevant to this, or get cleared once and for all (so that I have a reference when reporting):
One person you mentioned in your other thread is pedrillo0. This person's most recent post is in a
thread that he created. The thread has a total of 68 posts, all of which are written by him. The issue of using automated translation tools aside, making this many consecutive posts is obviously not acceptable. This person can write the OP, and any reserved posts, he can subsequently bump his thread by giving an update/news, but if no one posts in his thread after he writes the update/news, if he wants to post in his thread again, he needs to remove his previous post with an update/news, and if desired, he can consolidate the information into a single new post.
I've actually had talks in the past with a few mods about this (not focusing on this particular user) and it's entirely up to the mod. A thread made of 10+ pages of just updates CAN be considered spam, but since every post is an update and is usually separated by 24+ hours, it does not count as a "bump" or multipost. Fine print sucks.
I'll go a bit further and add a few more "local" (since they are local-board based) examples
Example 1 (last 3 updates are from today; so <24h between updates)
Example 2 (>24h separation between updates)
Example 3 (thank god this stopped being updated)
PS: sorry, my intention is not to highjack the thread .
I'd love to see an "official" answer here as a future refence
