If pianistimo's posts bother you, just don't read them!! Sure it's a lot of scrolling, but you're up to it I think.
I'm sure if you look in the pages and pages and pages of threads that this will have come up in before, the response to the 'why not just ignore it?' will be something like :-
(a) that the posts aren't ignored by others and so the "single post to just ignore" quickly becomes a subthread or more.
(b) that the person doesn't want to ignore the posts in the right place [for their definition of right], it's just that they want to be able to discuss other subjects, and this topic often prevents that.
(c) That they also want to read p's other posts that aren't ranting about religion and thus can't ignore them.
(d) That...and so on and so on.
Someone should create one of the multi-choice answers for these like they have elsewhere for the myriad 'why don't you just...' unworkable solutions to spam. I doubt anything new is going to turn up, hence, I guess, the reason for the requested poll.
My last word, just report the messages / threads you don't like to Nils. If he feels the same he'll delete / move them [and if there are enough and he has to keep deleting or moving and the person making them doesn't get the message then he'll probably get bored and ban the account that posts them instead] OTOH, if he doesn't feel there's anything wrong with them and folk keep reporting them then he'll probably get equally bored playing and ban anyone who continually reports them.
Whatever, of the 3 [or possibly more if we did a poll] that will take a role of 'reporting posts', 'moderating' and 'making posts' they will get to duck it out amongst themselves, with Nils picking the lucky winner(s) via his admin tools
