Jesus, all the people here saying never to lie on your resume must live pretty privileged lives.
Yes, its okay to lie, if you can back it up.
For example, I know just about everything there is about computers/sysadmin there is under the sun (im a born computer geek) but I never had any official degrees for it. I lied and said I had most of the CompTIA certifications and not a single person ever asked to actually see it. I already know everything that's in those books so it's not like I didn't have the knowledge, I just didn't have the stupid piece of paper, that, again, no one ever asked for.
Most employers are going to be exploiting your labor anyways so if you can take advantage of them you should, because they certainly going to be taken advantage of you, and you shouldn't feel bad for them.
As others have said, just keep it reasonable and don't lie yourself into a corner. If you don't know rocket science don't say you do and obvious things like that.
I generally trust riseup, but there's no guarantee. if you want a guarantee you have to pay for it (after doing proper research).
IIRC the $10/yr fee is just for hosting. You should be able to host it yourself for free. At $10/yr tho, even if I'm self hosting I'd pay that just to help development
I've been a member of their patreon for a while now, and I can attest that all their maps are excellent.
