They do this is an attempt to hide their plagiarism and make it harder to detect. It's still plagiarism.

Signatures from lower ranks should be removed as 99% of the copy and pasting is from Junior Members. Users should only be allowed a signature once they've earned it. Either that or there needs to be some punishments for the campaigns and their managers that accept and pay for this continually. Any half decent campaign manager wouldn't even allow Junior Members in the first place, or certainly not ones that were making this kind of garbled nonsense. Users should be checked before they're accepted and denied if their posts are all one/two liners or utter lazy nonsense. If this happened then we wouldn't have this issue. The longer we sit back and do nothing the worse it's going to get and it gets worse week by week as this sort of abuse is becoming commonplace and dozens are being caught and banned for it every day. There will be many more that evade detection, especially in the recesses of the local boards etc.
