Is it necessary to use the anti spam program more than once on a family's computers? Once it is installed, does it need upgrading periodically - hence the need to rebuy it?

I did buy antispam program (one to each of my families), and I didn't see any more spams afterwards. I don't think you need to buy it more than once.

It is rather annoying to keep seeing the anti-spam software appearing in the store once it's been bought, especially as it takes up a slot that could be used for something else.

In the early days of running my games I had to make a note of which ones had installed it so that I didn't buy it twice by accident, thinking I was in a different slot. Now, of course, I know I don't need it, unless I decide to start a new game.

It's actually kind of useful. It's only $170 or something like that, and they celebrate it like a house upgrade, which means their happiness goes up. I buy it when it comes up.

I am pretty sure I used this with my male with a spammer career and once I installed it he made money more quickly. Can a moderator maybe confirm that is correct or am I seeing things?
