经过多次尝试后，蒸汽社区市场是否阻止了客户？

Question

我正在用Java编写一个程序来解析来自Steam社区市场网页的数据。我知道如果连接在一定时期内进入市场的次数太多，那么蒸汽社区市场会在一段时间内阻止连接。现在，我的程序每250毫秒访问一个网页，在切换到另一个代理之前它将执行10次。我的问题是，即使我切换代理，我仍然会得到http错误429（请求太多）。我知道代理切换有效，因为我从http://checkip.amazonaws.com访问我的ip，它将返回新代理的ip。蒸汽社区市场是否会阻止客户以及连接？有办法解决这个问题吗？

以下是代码：

               switch(proxyInt){
                    case 0:
                        System.out.println("default");
                        break;
                    case 1:
                        System.setProperty("http.proxyHost", "104.238.131.206");
                        System.setProperty("http.proxyPort", "8080");
                        break;
                    case 2:
                        System.setProperty("http.proxyHost", "158.85.241.82");
                        System.setProperty("http.proxyPort", "1080");
                        break;
                    case 3:
                        System.setProperty("http.proxyHost", "45.63.85.44");
                        System.setProperty("http.proxyPort", "3128");
                        break;
                }

                URL whatismyip = new URL("http://checkip.amazonaws.com");
                BufferedReader ins = new BufferedReader(new InputStreamReader(whatismyip.openStream()));
                String ip = ins.readLine();
                System.out.println(ip);

                URL url = new URL("http://steamcommunity.com/market/priceoverview/?currency=1&appid=730&market_hash_name=" + skins[x].substring(46));
                BufferedReader in = new BufferedReader(new InputStreamReader(url.openStream()));
                String gun = in.readLine();

                skinsLowest[x] = moneyLowest(gun);
                skinsMedian[x] = moneyMedian(gun);
                skinsProfit[x] = skinsMedian[x] * .87 - skinsLowest[x];

                lowestPrices[x].setText(skinsLowest[x] + "");
                medianPrices[x].setText(skinsMedian[x] + "");
                String round = skinsProfit[x] + "";
                profitPrices[x].setText(round.substring(0, 5));

                System.out.println("Lowest: " + skinsLowest[x]);
                System.out.println("Median: " + skinsMedian[x]);

                repaint();

                if(x % 10 == 0 && x != 0)
                    proxyInt++;

                if(x == amount)
                    x = 0;
                else
                    x++;
