But I don’t really like that solution.

I think I might change my approach and make a new commenting policy rule. A quite simple one at that: Every comment that uses some kind of product name as their “name” will be deleted (also those who were made before today), no questions asked, and I re-establish the DoFollow plugin.

I can always delete the links that lead to sites I don’t want to support afterwards, although I’d of course need to introduce an explicit disclaimer for that as well. (Luckily, my current disclaimer reads “I reserve the right to delete spam as I see fit, even if it’s handcrafted”, so I won’t break any promises if I delete things that are spammier than I like retroactively).

On the other hand, I really love your contributions, and I really don’t want to make contributing with comments harder than it apparently already is…

What do you think? How do you handle that kind of thing in your own blog(s)?
