You are making assumptions which happen to be wrong.

1.  I never, ever get bots on forum posts. I always uncheck that option.  I find those emails annoying and silly.  If I want to follow the thread, I will open it.  I don't need an email every time someone replies.  I follow this policy on ALL forums I particpate in.

2.  No, they don't send 3-5 newsletters per day.  That's the problem.  If I WAS a newsletter I wouldn't have a problem.  But, Renderosity took that permission for a daily/weekly/whatever newsletter to mean anything Renderosity deemed important.  They exceeded the permission I gave them for a newsletter and a newsletter ONLY.

3.  Galleries.....sorry, I have nothing in galleries at Renderosity.  Eliminates that.

 

Quote - It does take a bit of time depending on the site protocols to stop receiving emails.

They send out several per week, depending on if you are a prime member or not.  That's not spam, it's newsletters you sign up for.  They don't send 3-5 newsletters per day, never have.

Messages however are a different story and that has to do with your habits not Rendo's.  You can receive notices for replies to forum postings and for gallery comments etc.  That isn't spam levels, you can, again, turn those off on site.

Spam is not a newsletter, SPAM is when you get something that you didn't opt in for and never requested.  Notices from Rendo are not technically spam, except for this new one about what you've looked at.

If you don't want to receive various messages then turn them all off - problem solved. However, realize that when you do so it can take a few days to clear out of the queue in the system, depending on how they have it set up.

No isp blocks a site for spam unless they receive multiple complaints, in cases like this they are usually sone by people who can't be bothered to turn off notifications or who leave and have an axe to grind with a company.
