Although i am quite a lurker in Lemmy, i don't have the time to be an active contributor, nor i wish to give away too much personal information nor i want to add an unnecessary addiction into my life, which is why i don't maintain a permanent account. However i do periodically have questions that I feel like only communities from Lemmy would be able to answer to my satisfaction, which is why i create burner accounts in my private window which i close after i am done with it. But after creating many such accounts for this purpose, i feel like i am not doing it properly. I feel guilty abandoning accounts that take up space in servers of instances which are constantly fighting against spam and DDOS attacks; it feels like i am participating in the attack too. However i believe i should not delete the posts, for it may come useful for me in the future and for other people browsing the communities. What methods should i adopt to further make my use of burner accounts in Lemmy more beneficial to me (in terms of anonymity and future account creations) as well as others (instances in terms of spam and members in terms of posts/comments)? Should I maintain a single account or permanently delete these accounts once i'm done with them? For context, I use a VPN and Tor Browser and a disposable email for instances requiring email for account creation.

I've been using Adobe Acrobat (cracked) for around 2 years, and i have recently started switching all of my proprietary apps with privacy respecting and/or FOSS apps, however i could not find a PDF viewer/editor desktop app that could scan and create documents from my printer/scanner, which i use quite often, thus i came here looking for a recommendation. Apart from scanning, i don't have much uses with a PDF editor. I haven't had to sign documents, share or work with it along someone, add watermarks or add read-only modes, though i wouldn't say i need them, for i may some time in the future. I just need a PDF viewer/editor which i can rely on. It should at least be able to scan documents as well as edit those scanned pages (cropping, color shading, rescanning etc.) and have a nice UI overall as i am not a power user who works with compact view modes or terminals. Thanks for the suggestions in advance.
