It was only a matter of time before the annoying bots of the gold sellers in WoW Classic would run rampant. But today, in 2019, these shady vendors are more intrusive than they were 15 years ago. They use modern tricks.
This is how gold sellers annoy players: Bots from trading sites that sell gold for real money in WoW Classic now use a blatant technique. They randomly invite complete strangers into chat rooms.
When the invitation pops up, a request immediately appears on the player’s screen asking if they want to join the chat room, similar to a guild invitation. The twist is that these chat rooms directly bear the name of the website that wants to sell gold for real money.

When Classic was new 15 years ago, players would occasionally receive a whisper from an ominous character as a form of harassment. This could simply be ignored by right-clicking.
With the new method, that’s no longer possible, as players can’t interact with the names of the spammers. A quick ignore and report via right-click is no longer possible. Only under Interface => Contacts can you block “channel invitations.”
What should I do if I am invited? Trading gold for real money is against the guidelines. If you receive such a chat invitation, do not join it and especially do not visit the advertised site.
Aside from the risk that your account could be banned if you buy gold, you run the risk of hitting a site infected with viruses and malware that damages your computer.

That didn’t work before
This is why it works today: The technique that gold sellers use is new. It is related to the communities introduced in Battle for Azeroth. This feature allows for the creation of chat rooms so that players can communicate across Battle.net.
These chats from the community feature also work in WoW Classic. Random players can simply be invited by chance. This way, bots can also easily spam you in WoW Classic.
This is what Blizzard is doing about it: Already at the release of WoW Classic, Blizzard took measures to combat gold sellers. This included a quirky change that made corpses disappear faster so that bots cannot use them for messages.
In the retail version of WoW, Blizzard has fought against trading with the WoW Token, a legal way to purchase gold for real money.
A token does not yet exist for WoW Classic, but some players suspect that it will come in the future.
