3. Notification letters will be sent out continuously. No matter whether you reply or not, you usually send a notice letter first, then an urgent notice letter, or a lawyer's letter (also fake, usually in the name of Lingyun Law Firm, because they helped CAD fight some lawsuits many years ago, but please remember that it was before).
4. The next step is to make a phone call. In the name of the so-called Autodesk legal affairs, use all kinds of threats, such as grasping the evidence of your infringement and letting the industry and commerce collect evidence at home, Barabara (these are all sales methods, and the actual industry and commerce department nominally manages the bureau of letters and calls regardless of copyright, but will not manage such things).
5. coping strategies: just ignore them, and the notification letter can be directly rejected, returned or thrown into the trash can. Call back directly, don't be afraid, they just want you to be afraid, remember that the caller is sales, sales, sales! Not the so-called legal affairs.
finally, it's really wrong to use pirated software, but these agents will cast their nets by this inferior means whether you use it or not, which is extremely shameful.
if you really need to use it, please go to Autodesk official website to buy it. The price is cheaper than offline. The shameless offline agent AutoCAD costs more than 1, yuan/year (even 2,, 3,, 51, years), while official website only costs 5, yuan/year (if you buy more, you can get a discount), or you can buy domestic products (a set of several thousand dollars is still permanently authorized). It is enough to have relevant genuine industry software, even the copyright department will not be difficult for you. Finally, despise shameless agents again!
