Crowdfunding website Kickstarter has surprised some of its users by replying to complaints they made seven years ago.
Many focused on a book which attracted huge numbers of complaints about encouraging sexual assault.
Users who received responses to long-expired projects from 2013 took to Twitter to congratulate the company on its response times.
Kickstarter said the emails were "auto-generated in error".
"The emails folks received yesterday was due to an unfortunate human error while working on a clean-up task completely unrelated to the ticket from 2013," a company spokeswoman said.
"It's important to remember we are still a small team at Kickstarter and mistakes can happen."
But some of the complaints related to sensitive topics, annoying many who suddenly received a reminder.
The most prominent example cited online was about a book by a so-called "pick-up artist" that encouraged aggressive sexual behaviour.
The error dredged up an old argument over the book, which Kickstarter had refused to cancel on its platform, eventually publishing a blog post admitting a mistake on its part. But, by then, the creator had already received the money.
