Hi thiesdewaard, no need to be alarmed but yes, you're basically right.
It wasn't just someone reviving an old thread but a type of pre-attack test run spam (which was reported as soon as I saw it - I've seen it many times in my time with websites I've been responsible for).
It's nuts - and we all are likely to fall for this at some time. (I rarely think to check if a thread is old - nobody does that usually). And it doesn't have to be an old thread - could just be any thread.
But as Key Fumbler mentioned, this one could have been automated in that, some program may have searched for some ordinary text 'anywhere' in the forum (possibly relating to a keyword - for yet unknown reasons) and then copy/pasted it.. and maybe the spammers take note of which forum members reply, or how long the moderators leave up the posting - all kinds of things (data) which I'll give a few outlines about below, since it is so strange.
Feel assured though, that neither you, nor any of us members did anything wrong here, except the spammer(s).
Details below because it's kind of fascinating if you haven't come across this kind of thing before.
BTW thought, there's no harm for readers now, nor in the first instance, and esp. since the post was deleted - maybe also the account - so they're unlikely to be able to post links or any other phishing scams now (thanks to fast action by the good mods).
While it's strange for an old thread to be brought back to life with some copy/pasted text or other ordinary looking post - it's often just a spammer (person or group) trying to establish a "normal" account with posting privileges. It can sit un-used for any given time.
One variation, or trick is, that some time later (hours/days.. years even) they return to any number of these accounts to massively post numerous threads filled with scammy/spammy links to total junk (often illegal and vile, other spammers' seedy offerings or trackers to try to phish people etc.).
It could just be done one by one by singular people for their own stupid spam 'business' or working for a spam group - and all these 'normal' looking accounts can even be bundled up in lists for example, in lots of many thousands and sold on to other spammers who are buying lists for 'easy' ways to then automate mass spamming attacks to all those accounts across many forums. In sales, it's a "pre-qualified customer list" - in spam-land it's "sitting duck target list".
Some low-level hacks pay some poor unfortunate or stupid people something like 1 cent per "clean account" they create (so these poor saps spend all day and night for weeks/months trying to earn money they couldn't get otherwise in their hard situation), then the irredeemable 'boss' can then sell those lists for astoundingly more per acct. to many other crumbs. They may have lists for all kinds of industries, interests etc.. just like pay-per-click advertising.
Alternatively, and not something you'd want to believe - but it's a small possibility that some crazy person who thinks they are a competitor of Pianoteq may have hired an "SEO" (search engine optimization) company/person, specifically to attack this forum (to lower the search page ranking esp. if they succeed in flooding the whole forum with junk using maybe many other 'normal' accounts they set up even some months ago).
Some people hiring SEO firms may not know that their outsourced SEO team may engage in this kind of "Negative SEO" practice, without consent it's possible too - A competitor who hired these guys can say "We didn't know our SEO team would be doing such a thing - I'm shocked, shocked!". Plausible deniability.
But we'll not likely find out which of those it may have been, unless the other suspicious recent copy/paste postings also have similar network details in the forum log files maybe. I'd recommend the Modartt people check in case it can be shown that other accounts are linked (by I.P. address and other fingerprints etc.).
It's all crazy stuff - and it's nuts that it happens but for readers, there's usually not so much danger if these accounts are stopped before they are 'used' to post links.
I've noticed over lots of years running websites that innocent posts can suddenly begin to be "edited" later too, to add scammy links into the text... you hardly see it as a normal reader.. but it's not that they need people to see the link, or click them, IF the goal is to send "Negative SEO" signals to for example Google. Search engine indexing robots DO see these links and can heavily punish the search listing ranking if a site is peppered with this kind of petty nonsense spam.
It's also possible that some strange person just likes doing it as a hobby - to waste the time of people like Niclas who have better things to be doing. Checking logs for matches of existing users can expose those pretty instantly.
