The one caveat to building is if you build a PC and a single component is faulty, you are now responsible for determining which component is to get the RMA done. That can be a big hassle. One time for me it was actually two different components that needed to be replaced by the manufacturers, and that was a pain to figure out.
This part is directly Telegram’s fault. If they cannot keep up with their moderation queue then they need a bigger moderation team. Preferably properly remunerated. There are news reports about how Facebook’s sub-contracted moderators work for these extremely shitty companies who track them based on how many reviews a minute they do, and which causes extreme psychological damage to the workers both because of the extreme content they have to see as part of their jobs and the bad working conditions they must put up with.
